Poly M22 Amplifier Insider Info:
TECH REVIEW – When we demo any H-series headset, we always use the M22 Vista amplifier in lieu of a Direct Connect cable. The reason is an amplifier will be compatible with almost any phone, and it gives you complete volume control. Most phones have a speaker adjustment, but few, if any, have microphone volume control. With the M22 you control everything, so you and your caller hear each other perfectly. The M22 amplifier also uses a compatibility switch so it’s quick and easy to find a setting to make your system work. This is especially useful for users that travel and plug into multiple telephones. Have you ever had to interact with a co-worker and find yourself constantly trying to cover the mouthpiece of your handset? With the M22 amplifier, you have a mute button to take care of this problem, and it completely shuts off the microphone so you’ll have complete confidence your caller won’t hear your conversation. The M22 uses two AA batteries for power that will last for years. It’s also good to know that as the batteries become weak, you will hear beeps in your headset to indicate a battery change is needed. You’ll have days, if not weeks, to replace the batteries and will only notice a slight decrease in quality.
HOW TO INSTALL – When using the M22 amplifier on older phones, you will plug the telephone cable (or pig-tail cable) into where your handset plugs into your phone. This typically means you will remove the handset from your phone to use your headset, and place the handset back in the cradle to hang up calls. On newer phones with a headset port, you will use this port and typically push the ringing line or a headset button to initiate and terminate calls. Install 2 AA batteries in the side compartment (+ facing outward on the top battery and – facing outward on the bottom battery) and slide the battery cover into place. Next start with the compatibility switch (located on the side) on setting 5, which is the most universal. Plug your headset into the M22’s coiled cable at the Quick Disconnect connection and lift your handset (on older phones) or press an available line on newer phones. You should have a dial tone. If not, slide the compatibility switch to the other numbers labeled 1-6, using the white pick tool located on the bottom of the M22 amplifier, until you have a dial tone. Once you have a dial tone, call a co-worker and adjust your microphone volume. Once the compatibility switch and microphone volume settings are complete, slide the included cover over them to ensure they’re not accidentally changed. You are now set for years of use with your Poly M22 Vista amplifier.
HOW TO CLEAN – When cleaning your Poly/Plantronics M22 amplifier, always use non-alcohol chemicals or wipes. Using alcohol-based products over time will break down the cords making them very stiff and clumsy to use. You will want to wipe all plastic components and cables, but avoid saturating any openings where electronic components are in close proximity. For the M22 amplifier, this will include around the speaker volume dial and other buttons located on the top of the amplifier. An old toothbrush works very well to clean dust build up from the groves in the casing. When cleaning your M22 amplifier, also avoid sticking anything into the end of the Quick-Disconnect connection where the four metal contacts are located. This connection is made to last, and more damage than good will come if you try to clean it.
WHO USES THIS MODEL – The M22 amplifier is used by business professionals that require the best possible audio sound quality. It’s compatible with most phones, making your life much easier, versus using a Direct Connect cable, which requires determining compatibility and then hoping the volumes are adequate.
