MISCELLANEOUS INFORMATION

ular feature operates, contact your system operator. The only user- programmable feature of this transceiver is the seven telephone numbers (if your transceiver is equipped with the optional telephone keypad). However, even that may not be user programmable if the location has been locked by your system operator (see “Storing and Recalling Numbers From Memory” on page 18).

Setting Volume Level

This transceiver does not have a squelch control that can be turned to enable background noise for use in setting the volume level. However, if the key press tone is enabled, any key can be pressed and a beep will sound that is representative of the current volume level. The index on the volume knob can also be used to determine the current volume setting.

Display Messages

Messages may appear in the display which indicate operating modes and error conditions. The messages that may be displayed are as follows. Refer to the related descriptions in this manual for more information.

NO SITE - Indicates an out-of-range condition. The intercept tone also sounds when this message is displayed. To correct this condition so that calls can again be placed, you must get closer to your repeater site. This message is not displayed in the conventional mode.

BUSY - Indicates that the system being accessed is busy. Calls cannot be placed until the system becomes available. Refer to “Clear-To-Talk” on page 24 for more information. This message is not displayed in the conventional mode.

TX TIME - Indicates that the transmitter has been disabled by the time- out timer.

TX DSBL - Indicates that transmitting is not allowed on the selected group because it has been programmed as receive-only. This message is displayed in the conventional mode only.
