OPTION SWITCHES AND MENU MODE

One use of the time-out timer feature is to prevent a repeater from being kept busy for an extended period by an accidentally keyed trans- mitter. It can also prevent possible damage to the transmitter caused by transmitting for an excessively long period.

Tone Select

If the TONES menu parameter is selectable, the tones that sound can be selected. Otherwise, the tones that sound are fixed by programming. The following choices are available. Refer to page 33 for more informa- tion on using the menu mode.

Silent - All tones are disabled.

Key Beep - Only the Select switch and key press tones are enabled. Alert - All tones except the preceding Key Beep tones are enabled. All Tones - Both the Key Beep and Alert tones are enabled.

Transmitter Thermal Foldback

If the transmitter temperature increases to the point where damage to the transceiver could result, power is automatically cut back. When this happens, the transmit indicator on the front panel is orange instead of red when the transmitter is keyed. After sufficient cooling occurs, power output returns to the normal level and the indicator changes back to red. One time when this indication could occur is if you transmit for an extended period.
