release the captive screw in the battery
compartment cover.
- Remove the battery compartment cover.
- Remove the old batteries from the compartment.
- Insert the new set of batteries into the battery
compartment ensuring that the battery polarity
matches the marking on the inside of the battery
compartment.
- Relocate the battery cover over the battery
compartment and fasten in position with the
battery cover captive screw.
This unit will contain Nickel Metal Hydride

(NiMH) batteries. Do not dispose of these
batteries with other solid waste. Used
batteries should be disposed of by a qualified
recycler or hazardous materials handler.
16.6 Replacing All Fuses.
If, during one of the powered tests, a message appears

stating that incoming mains is missing it is possible that
one of the fuses has blown. All fuses should be checked
- 86 -
and replaced where necessary.
There are 3 fuses, one in the mains plug and 2 internal

fuses. The mains plug fuse is replaced in the same way
any plug top fuse is replaced. The internal fuses should
be replaced as follows:
