OPTIONS
Type 99 Option
If the Type 99 Option is present, individual selective calling is possible. Press the programmed Flex key or use the menu and CHANNEL/SEL keys to enable the decoder option (Scan must be off). The LED display will show the option status: "T99 ON" or "T99 OFF". Press the button a second time to toggle the option status. The display will revert to normal channel display after 5 seconds. When a call is received, an alert tone will be heard and the display will flash, alternately "T99" and the channel selected. After receiving the call, press the CLR button to reset the decoder for the next call. The display will stop flashing.
If a call was received and the display is flashing, the CLR button must first be pushed before the T99 option may be disabled.
If the Horn Alert option is present with the Type 99 option, the radio can beep the vehicle horn when a Type 99 call is received. This option permits alerting persons out of the vehicle when a call is received. The Horn ON/OFF switch which is mounted on or near the radio is used to turn off the horn beep relay.
Public Address Option
If the Public Address Option is present, the radio may be used as a public address amplifier. Press the programmed Flex key (or use the menu) to enable the option (Scan must be off). The display will show "PUB ADDR". When the microphone PTT switch is keyed, the radio no longer transmits, but allows the microphone audio to feed the speaker. Adjust the VOLUME for desired level. Press the Flex key or use the CHANNEL/SEL a second time to disable the option. The display will revert to normal channel display. Changing channels or turning scan on will also turn the option off.
The public address microphone audio normally feeds an external speaker. An ON/OFF switch, which is mounted on or near the radio, allows selecting either the internal or external speaker for the receiver audio. The ON/OFF switch turns the receiver audio on or off to the external speaker. This switch still functions for the receiver audio with the PA option disabled.
