A: Yes, the CS540 comes with a headband and three different size ear loops. Q: Does the CS540 come with all the cables and other items I need to connect to my phone, or do I need to buy anything else? A: The CS540 comes with everything you need to connect the unit to your phone, however, if you want to answer remotely (away from your desk), you will need an HL10 handset lifter or an EHS cable. These two options are dependent on your phone, so give us a call to determine the correct connection for your phone, or visit our compatibility page at: Headset Compatibility Guides. Q: We don’t have “tech” people in our office, will I be able to set the headset up by myself? A: Yes, this headset system is very easy to set up, and we even put together a CS540 Setup Guide with detailed pictures. Q: Will I have interference if there are two CS540’s in the office? It is a very small office. A: There will be no interference with two headsets, in fact, you can have up to 38 headsets in close proximity. You can also mix in CS540-XD units, which use a different frequency, to have an additional 54 units in one area without issues. Q: How well does the CS540 keep outside noises out? A: The CS540 has a noise canceling that reduces background noise by up to 75%. If you’re in a busy office, your callers will hear you clearly and only hear the mumbling of co-workers in the background. Q: Is there a way to adjust the speaker volume on the calls? A: Yes, it includes great volume control for crystal clear communications. First, your major speaker adjustment is on the base. This is typically set when you install the unit. Second, on the headset itself is a speaker volume switch for minor adjustments for adjusting call to call. Last, you can also use your phone’s volume button to increase/decrease volume. Q: Will I be able to adjust the volume of my voice? A: Yes, on the bottom of the headset base there are dials for listening volume, as well as microphone volume. Q: Can I use the headset on just the right ear? A: Yes, the headset can be worn on either the right or left ear by simply rotating the earpiece. Q: How do I put a call on hold while answering another call? Do I have to be at my desk to do that? A: Putting a call on hold is a phone function and must be done at your phone. Q: Is there a way to tell when I mute the headset? I really need to know for sure that my headset is muted at times. A: Yes, when the wireless telephone headset is muted, a solid red light will show on the base, and you will hear three high tones through the headset. Q: Is the wireless signal from the CS540 secure? A: Yes, the CS540 incorporates DECT technology making it the most secure wireless telephone headset on the market, while also eliminating interference. Q: If I need to go to another room, may I put the call on hold and answer it from another phone? A: No, the base is tied to one phone, and in order to continue to use the headset, you must retake the call from the same phone, however, you can pick up the phone from a different location without the headset. Q: The CS540 says it comes with a charging base, but does it come with a power adapter? A: Yes, the A/C adapter is included with the CS540 Q: Is the charging base included in the box, or is this just the headset piece? A: Yes, the CS540 comes with the charging base, if purchased from an authorized distributor. Q: We want to use just one base with two CS540’s – is this possible? A: You can pair a spare headset to the same base for conference calls, but you can not use two headsets with the same base to take calls. You will need to consider a second charging base to make sure both units are fully charged and ready to use at any time. Q: I share a job with someone else (we have different hours). Can we both use the same headset during our individual shifts, or do we need two different headsets? A: You may use the same headset if you like, however, for sanitary reasons we have options to utilize individual headsets. Call us at 800-914-7996 to discuss this option. Q: Can I use the headset while it is being charged? A: No, the wireless telephone headset has to be placed in the base to charge, however, if you receive a call, you may take it out of the base to use for that call and continue charging after the call. Q: How long is the warranty? A: The Plantronics CS540 has a one year warranty, when purchased through an Authorized Distributor. Q: Can I buy just the headset part without the base? A: Yes, you can find the replacement headset at: CS540 Replacement Headset. Q: I currently use a Plantronics CS50, would the CS540 be a compatible upgrade? A: Yes, the CS540 is the newer version of the CS50 by two generations. It works and functions the same, with improved sound quality, comfort, battery management, and distance. If you are using an EHS cable with your CS50, you will need to update it as well, because it physically will not plug into the newer CS540. Q: What headset options are included in the Plantronics CS500 series of wireless headsets? A: CS510 (single ear over the head), CS520 (dual ear over the head), CS530 (over the ear/in the ear) and CS540 (convertible – over the ear/in the ear and single ear over the head). 2) Compatibility Questions: Q: Does this work with any corded phone? A: Generally speaking, yes it will work with any corded phone that either has a headset port or a handset that uses a standard RJ9 plug you can remove. Give us a call or confirm compatibility at Headset Compatibility Guides. Q: Does this headset work on most cell phones? A: No, the CS540 is for desk phones. The W700 series will allow cell phone usage. Q: Can the CS540 connect to my PC to use with software like Skype? A: The CS540 is traditionally used with your desk phone. However, if you would like to use it with your PC, you can purchase the Savi D100 USB Dongle or the APU-75 EHS cable. Please note when using this cable, you are not able to simultaneously connect to your desk phone. Q: Will this headset connect via Bluetooth with most desk phones? A: No, it uses DECT wireless technology, which allows you to roam up to 350 ft from the base. Q: When my work phone rings, my wired headset automatically places me into the call. Does the CS540 headset do this also? A: There is an auto answer switch on the back of the charging base. The factory has it set for no-auto answer (red), but you can change that by moving the switch to green, and it will answer when the headset is removed from the cradle.

A: Yes, you can have up to 38 headsets in close proximity, and adding CS540-XD into your environment can add an additional 54 units. Q: What is the 3.5mm jack on the back of the base for? Can I use a headset with a 3.5mm jack there? A: No, you can not use a 3.5mm headset in this port. The 3.5mm jack is for a busy light or the handset lifter / EHS cable to plug into. Q: Can I use the CS540 with my iPhone 6? A: The CS540 is designed to work with desk phones. The W740 wireless headsets will allow you to use your iPhone as well as a PC.

Q: Will I be able to listen to music on this headset? A: No, it only connects to your desk phone; itunes and Spotify won’t work. Q: Does the headset plug in using an audio jack or phone line? A: The CS540 uses an RJ9 plug (the smaller modular plug just like your handset) that will plug into a designated headset port or plug into where your handset currently plugs into. Q: Is the CS540 Bluetooth? A: No, it is DECT Technology which runs on a different frequency than Bluetooth and provides much greater range. Q: Can I use this headset with a cordless phone? A: No, You need a phone with an RJ9 handset receiver or headset jack. Q: Can I use this with my landline phone at home?

You may also be able to use a Plantronics TR-11 EHS cable for remote answer/hangup, if using standard copper phone lines. We continue to experience issues with TR-11 and cable modems using VoIP phone services like Vonage. Q: Do we need multiple bases to hook up more than one headset? A: Yes, you need one headset / base per phone, but for conference calls you can join up to three additional headsets per base. Q: Can the CS540 be used on a multi-line phone (6 lines)? A: Yes, the CS540 can be used on multi-line phones. Q: My Cisco phone has a 2.5mm jack, may I use the CS540? A: Yes, the CS540 will plug in through the handset jack on your phone. Q: I work in a very loud office, and I am afraid I won’t be able to hear the calls with one ear exposed to the noise. A: You may wish to look at the CS510 or CS520, if loud office noise is a concern. Those headsets will cover more of your ear, allowing you to focus on your call. Q: I have an XBlue phone with a 2.5mm jack, will the CS540 work? The manual says I don’t need a lifter. A: Yes, the CS540’s interface cable plugs into the RJ9 handset jack of your phone. Most XBlue phones are not compatible with handset lifters or EHS cables. Call us at 800-914-7996 with your XBlue model number, and we will check compatibility for you. Q: I currently use the flash button on my phone for conference calls. Will the Plantronics headset CS540 be able to pick up the other party caller while I am on the phone? A: Yes, the CS540 will work for conference calls, because we’re simply changing how you talk (headset instead of handset), so your phone functions exactly the same.
