Installation and Operator Handbook 4 4.1 Operating Instructions OPERATING INSTRUCTIONS INTRODUCTION After installation (as described in Chapter 3), normal operation of the DRB-25 is achieved by applying power to the DRB-25 and switching on the rear panel power switch and the Power Supply Modules. The DRB-25 Modules will perform self-test diagnostics after power is applied. Visual indicators on the module front panels will convey the status of the DRB-25 to the Operator.

Switch on each Power Supply Module Note that DC direct configurations have no power supplies or switches. 4.3.1 Initial Power-On Checklist Refer to Table 4-2 to verify that power indications are correct. Should displays or indicators suggest a fault condition, refer to 4.3.2 before proceeding. The DRB-25 performs a self test and warm-up routine at power-on.

See table B-1in Appendix B for likely cause and recommended action Fuse Replacement AC DRB-25 units are protected by a single fuse located on the IEC connector/switch module. To check and if required, replace the DRB-25 AC power fuse, proceed as follows: 1. Switch off all power to the DRB-25 and disconnect the Mains lead.

Installation and Operator Handbook Operating Instructions ENSURE ALL POWER IS SWITCHED OFF BEFORE ATTEMPTING TO WORK ON THE DRB-25.. 1. Switch off all power to the DRB-25 and disconnect the Mains lead. 2. Disconnect and remove the Interface Module from the rear of the DRB-25 cabinet. 3. Disconnect and remove the antenna system RF cables from the rear of the DRB-25. 4. Remove the four Philips head screws securing the left-hand rear panel of the DRB-25. 5.

Installation and Operator Handbook Indication DRB-25 fails to receive Failure of external interfaces AMX-MA-00654 Issue 0.02 (USA) Operating Instructions Probable Cause Recommended Action Antenna system failure Check antenna system for damage and ensure correct connections. Transceiver Module failure Switch power off, substitute known good Transceiver Module and re-test. Interface Module failure Switch power off, substitute known good Interface Module and re-test.

Installation and Operator Handbook 4.5 Operating Instructions CONFIGURATION If all the external indications are that the DRB-25 is operational, proceed with the configuration process using the Transceiver Module Programmer application as described in Chapter 5. Once configuration has been completed, the DRB-25 can be tested in its intended system environment. Channels may be configured as fixed channels or scan channels as described in Chapter 5. 4.5.

Installation and Operator Handbook 4.6.2 Operating Instructions Making Calls Calls may be sent from the DRB-25 using a microphone connected to the transceiver module front panel RJ45 audio connector. Calls will be broadcast with the transmit NAC and Talkgroup ID (digital mode) or transmit CTCSS/CDCSS (analog mode) of the transceiver’s current channel, as defined by the channel table entry in the Transceiver Module Programmer. 4.6.
