OPTION SWITCHES AND MENU MODE

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 32 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.

OPTION SWITCHES AND MENU

MODE

Option Switches

All five option switches on the front panel are programmable by your system operator. The available option switch and menu mode func- tions are shown in the table on page 31. Those which can be assigned to an option switch are indicated by an entry in the “Option Switch” column. Refer to the page listed in this table for a description of the func- tion. If a function is controlled by an option switch, it cannot be controlled by the menu mode and vice versa. Some switches may not be used.
