Page 15

GENERAL OPERATION

- Indicates that an option controlled by the AUX switch or OPTION menu parameter is enabled (see page 24).

- Indicates that a call has been received on a group programmed for a call indicator (see page 21). To turn this indication off, press any key.

- Indicates that the monitor mode is enabled. This mode disables Call Guard squelch and other squelch control features so that all messages are heard on conventional systems (see page 44).

GENERAL OPERATION

Power-Up Sequence

When power is turned on, the backlight turns on, all segments in the display are momentarily enabled, and the last seven digits of the transceiver part number are very briefly displayed. A beep then sounds (if tones are enabled) and the transceiver is operational.

Determining Volume Level

The relative volume setting can be determined by noting the position of the index on the volume knob. You may also be able to enable a reference tone or background noise for use in setting the volume. Proceed as follows:

•If key press tones are enabled, a short tone sounds when an option switch is pressed or the Select switch is pressed or rotated.

•If a conventional system is selected, take the microphone off-hook and if someone is using the channel, voice is heard. If no one is using the channel, the squelch control can be adjusted counter- clockwise as described in “Setting Squelch Control” on page 18 and noise is heard. It is not possible to unsquelch the transceiver in this manner when an LTR-Net or LTR system is selected.
