Hardware Related Problems

If the O5 / O3 / M5 Control Head displays alternating VR ERROR and Error Code (RC
ERROR XXXX or RF ERROR XXXX), turn the DVRS off and then back on. If it does not
correct the condition, note the exact error code and contact Futurecom to obtain an RMA
and further instructions.
In case of insufficient DVR Tx Power or poor sensitivity, please verify that the
frequencies programmed in the DVR are within the filtering specifications as indicated on
the duplexer and in-band filtering labels.
Ensure the DVR is only enabled on Mobile Radio Talk Groups using the frequency plan
for the specific DVR Model.

Primary EEPROM Map corrupted

Warning RC0400 displayed on the control head upon power up indicates that the
Primary EEPROM map of the DVR contains corrupted data. The DVR will still operate
properly from the backup EEPROM map. To fix the primary map, please use the latest
Tweaker to read the DVR. This will restore the Primary EEPROM Map.
VR Error RC1000 displayed permanently indicates that both the Primary and Backup
EEPROM maps are corrupted and the unit is not operation. Please contact Futurecom
for further instructions on how to troubleshoot the problem.

Firmware Upgrade.

Some DVRS units which were originally shipped with older firmware may require
EEPROM map upgrade after re-flashing them with newer firmware. To upgrade the
EEPROM, please follow the instructions shipped with the flash upgrade.
RC ERROR 4000 indicates that the DVR firmware has been updated but its
programmed personality has not. The DVR personality needs to be updated by reading
the unit with the Tweaker programming software in order to upgrade the EEPROM map
as described in the Firmware upgrade instructions provided by Futurecom.
