User manual PLANTRONICS A20

[. . . ] With the Accessory Deck Cover (23) removed, organise all related cables by pressing the cables into the moulded slots. The power Supply Cable and OLI Cable run towards the rear of the deck. Connect the other end of the Base Unit Cable (11) to your telephone's Handset Port. Push the Headset Stand (17) into the Headset Stand Location (22) that is most convenient for you to use. [. . . ] Press the Headset/Handset Selector Button (7) once to display indicator lights and talk normally. Note: If the Amplifier is left in the Headset mode, simply take the Handset off-hook to answer the call (see diagram A, page 1). You can optimise the performance of your Amplifier by stepping through the four configuration settings. The Configuration Dial (12) is located on the left side of the Amplifier in front of the handset jack. Place a call to a co-worker and while speaking turn the Configuration Dial (12) clockwise until you achieve the best sound. A paper clip can be used to make turning the configuration dial easier. Experimenting with these four settings will not harm the amplifier or your telephone. Your Amplifier provides both visual and audio feedback for all operator adjustments. EarCons provide audio feedback in the form of different toned beeping sounds for different functions. The intensity of the EarCon Audible Cue can be increased, lowered, or turned off (three levels plus off). Simply hold down the Mute Bar (6) then depress the Volume Rocker Switch (3) ( decreases volume or turns off EarCon; increases EarCon Volume) (see diagram E, page 1). Even though the user hears the EarCon, the calling party does not, even if you make adjustments midway through a call. Plug the AC Adapter into another wall outlet and ensure the power supply is switched on. Press the Headset/Handset Selector Button (7) at the front of the Amplifier to make sure Amplifier is in headset mode. Turn the Configuration Dial (12) on the left hand side of the adapter clockwise through each of the four positions until you hear dial tone. Check that all the cables are completely plugged in and in the correct port. If you don't hear these musical beeps there could be something wrong with the headset or adapter - call your supplier or local Plantronics office for help. Turn the Configuration Dial (12) on the left hand side of the adapter clockwise to the next setting until the dial tone can be heard normally. If both positions are the same then use the one you're currently in ­ they are both valid. Check that all the cables are fully connected and in their correct port. [. . . ] ensure that the voltage and frequency markings correspond to the local supply. The mains socket outlet must be installed near the equipment and must be easily accessible. Do not use the A20 with one piece telephones (telephones in which the dial keypad is part of the handset). Unplug the unit from the telephone set and the AC adapter from the mains supply before cleaning with a damp (not wet) cloth. [. . . ]
