User manual PLANTRONICS CA12CD/A

[. . . ] In other regions, the CA12CD/A operates in the DECTTM frequency band (1. 88 to 1. 90 GHz). Various versions of the CA12CD/A are available for use in specific countries. 1. 2 User density and range can vary widely due to such variables as building layout and whether other devices are operating in the same frequency band as the CA12CD/A. [. . . ] Properly adjusted audio levels are especially important for avoiding side-tone echo, as well as for being able to hear your callers and be heard clearly by them. 3. 6 The base unit and the remote unit are paired with each other at the factory in a process called subscription. If you replace your remote unit or if your remote unit loses its subscription (shown by a rapidly flashing on-off indicator), you can perform the subscription process as follows: · Hold both of the talk (sending) fine-adjust volume controls on the top of the base unit down. · Hold the remote unit's listen (receiving) fine-adjust volume control in either the up or down position. · The remote unit's on-off indicator will turn on steadily (no flashing). · The remote unit will subscribe to the base unit, after which the base power indicator will return to the steadily on state. The remote unit's on-off indicator will go out for a few seconds and then begin to flash slowly. Your CA12CD/A is now ready to use. 3. 1 To maximise user density, always turn the remote unit off when not in use. If the battery has just been installed, the remote unit will automatically turn on and the on-off indicator will begin to flash. (Reference section 1. 5) 3. 3 Pressing the push-to-talk (PTT) button on the remote unit will generate the "key" signal to your console or radio. While the PTT button is depressed, the green talk indicator on the base unit will illuminate. 3. 4 The operation of the PTT button can be adjusted with a screwdriver to be either lockable or non-lockable as shown. How to select the lockable or nonlockable switch position Lockable position Note that the selector slot is aligned vertically. The push-to-talk button can be pressed momentarily or locked in the ON position by first depressing then sliding the button until it locks. Non-lockable position Turn the selector horizontally. The push-to-talk button can be pressed momentarily when you wish to speak.
