3.4.3
Transmitting (Transmit Operation)
Note
: Transmission on any of the transceivers linked to the JA95-060 is only possible if the designated
transceiver (AUX in these examples) is selected on the main audio panel.
To select a transceiver, rotate the Transmit Select Switch until it aligns with the line leading to the Transceiver Select
switch legend (see
1
) - default legends AUX1, AUX2, AUX3, AUX4, or AUX5. The corresponding Transmit Select
annunciator will illuminate.
When the TX PTT input is activated, the unit will transmit on the selected transceiver, and the deadfront Transmit
Annunciator (
3
) will illuminate ‘TX’. All MIC and sidetone audio will be routed to the RX OUTPUT.
3.4.4
Transmit Operation, Duplex AUX5
Note
: If the AUX5 transceiver has been configured as duplex, it can be used with a cellphone or
sat-phone. Check your configuration with the installing agency.
If the unit has been configured for cellphone or sat-phone use and AUX5 has been selected for transmit, momentarily
activating the TX PTT will keep AUX5 transmitting. A second momentary activation of the TX PTT, or moving the
Transmit Selector away from AUX5, will stop the AUX5 from transmitting.
AUX5 Transmit timeout operation does not operate when AUX5 transmit mode is set to duplex.
3.5
Emergency Operation Mode
Emergency mode is entered automatically if power to the unit is lost.
3.5.1
Auto Emergency Mode
If the unit is in emergency mode because power has been lost to the unit, the AUX1 transceiver will be routed to the
RX OUTPUT. The TX microphone and TX transmit key are connected to the AUX1 transceiver. No other function in
the JA95-060 will operate when power is lost. All indicator LEDs, legends and annunciators will be dark.
