Using External +12 VDC Power with Battery Back-up
Note: An additional hole, strain relief, and conduit will need to be installed into the callbox.
The unit may be powered by an external source of 8 to 12 VDC. This
source should be filtered, with minimum noise and hum, and capable of
supplying at least 1 Ampere.

How the Callbox will operate:
How the Callbox will operate:
If External 8 to 12 VDC Power Fail Alert Feature is NOT ENABLED:
LOW battery detection can only occur when the external voltage is removed or failed.
Radio will only check for LOW battery or DEAD battery condition when the radio is ON.
If LOW battery is detected, a single tone Alert or voice message
will be transmitted at the end of the transmission.
Radio does NOT automatically transmit a LOW battery tone alert or voice message. The callbox must be ON and Alert or voice
message is only sent at the end of a transmission.
If DEAD battery is detected, the radio ceases all operation. A DEAD battery tone is heard on the callbox speaker and the radio
will turn OFF.
If External 8 to 12 VDC Power Fail Alert Feature is ENABLED:
Radio always checks for External voltage when the radio is ON. If loss of external voltage is detected while the radio is in
standby: a single Alert Tone or voice message
will be transmitted immediately.
If loss of external voltage is detected while the radio is in receive: a single Alert Tone will be transmitted after the received
message is complete.
If loss of external voltage is detected while the radio is in transmit: a single Alert Tone will be transmitted at the end of the
transmission.
Once loss of external voltage is detected and the Alert Tone is transmitted, the radio will automatically send the Alert Tone once
every hour until external voltage is restored or the batteries are exhausted. If radio is set for Automatic Turn-Off (default setting)
this hourly alert will NOT occur.
this hourly alert will NOT occur.
If Dead battery is detected the radio ceases all operation, a DEAD battery tone is heard on the callbox speaker and the radio will
turn OFF.
Using External 8 to 12 VDC Power without Battery Back-up
The Ritron RQX callbox can be programmed for always-on operation by disabling the Automatic Turn-Off option. This is
accomplished using the RQX PC Programmer, or through Field Programming. Once Automatic Turn-Off is disabled, the user
simply turns on the RQX by pressing the front panel PTT button and it will remain on as long as power is applied. If power to the
callbox is lost then restored, the user must press the front panel PTT to restart the radio. For externally powered callboxes, battery
backup is one method of keeping the radio on if the primary external power is lost.
For users that do not want to “restart” the callbox after a power loss, the callbox can be modified to automatically restart
after a power loss. By loading 15 k ohm in R628 the external power supply will automatically turn on if there is an input. Also
PJ602 must be in the “sensor turn-on” mode with the sensor input (pin 2 of PJ601) tied to ground. This configuration will also turn
the internal battery on if the external power fails. R628 need not be loaded if only internal batteries are used.

Important considerations before applying this modification:
Important considerations before applying this modification:
The Automatic Turn-Off option must be disabled.
When Automatic Turn-Off is disabled the unit will consume the largest amount of current, but is always ready to instantly receive
messages. This mode should only be considered if an external source of power is available. If internal batteries only are used, the
radio would work only a few days.
