5. Fuse Replacement
The BV1250 unit has one fuse which is located in the rear panel of the base unit.
The fuse protects the unit against over-voltages and power spikes. If the unit’s fuse
should burn out, it must be replaced but first, the service person should attempt to
diagnose the correct the underlying problem. This will usually have something to
do with the power supply to the unit.
NOTE
Before replacing the fuse, turn the power to the unit OFF,
taking care to use the Power-off procedure described in the
BV1250 Installation Guide, Section 4.9.
To replace a fuse:
1.
Unplug the unit’s power cord from the power outlet.
2.
Pull the fuse holder assembly out from the rear panel of the unit.
3.
Remove the fuse from the fuse holder and discard the failed fuse.
4.
Replace the 7 x 30 fuse with a fuse of the same specification.
5.
Reinsert the fuse into the fuse holder and reinstall the holder.
6.
Reconnect the power cable plug to the power outlet, and turn the unit power
switch to the ON position.
7.
Verify that the unit power is on and that the power-up cycle is correctly
completed as described in the BV1250 Installation Guide.
