Dimmer switch

The Dimmer switch on your clock radio will allow you to adjust the
intensity of the clock display to suit room brightness.

1. Use the High or Low buttons to adjust the intensity of the display.

Back-up battery
As with all batteries, eventually the built in lithium battery will need to be
replaced. A number of factors, such as the length of time between the
date your clock radio was manufactured and the date you plugged it in
for the first time, determine the amount of time before battery replacement.
During this initial storage period the lithium backup battery is supplying
power to your clock radio’s computer memory. Once you connect your
clock radio to the household AC mains supply the battery no longer
supplies power to your clock radio’s computer memory. A fresh backup
battery can supply power to your clock radio’s computer memory for 3
years even if it is never connected to a mains supply. If your clock radio
was connected to the AC mains supply within a few months after it was
manufactured and you experience only short interruptions to the mains
supply, your battery may last for up to 5 years or even longer.
When the battery drops below a certain level the Low battery indicator
will light. When you see this indicator you should change the battery as
soon as it is convenient to do so.
See following page for details on battery replacement.

cr9977 instruction book issue 2.PMD

3/16/2006, 2:09 PM

Changing the back-up battery
1. Purchase a replacement lithium backup battery type CR2032 or
equivalent.
2. Remove the new battery from its packaging so that it is ready to
install.
3. Important: Maintain connection to AC mains supply during battery
replacement. This will provide power whilst the original battery is
removed.
4. Use a small screwdriver to remove the small screw securing the
battery holder on cabinet base.
5. Remove the battery holder from cabinet.
6. Remove old battery from holder. Replace new battery with
facing direction shown in drawing opposite.

Fuse

Do not allow this unit to be exposed to moisture (e.g. dripping or
splashing) or to temperatures exceeding 70 degrees centigrade. It is
recommended that the FM band be used wherever possible as better
results in terms of quality and freedom from interference will usually be
obtained than on the MW band.

This apparatus must be protected by a 3A fuse (BS1362) in a 13A plug
(BS1363). If another type of plug is used a 5A fuse should be fitted in
the plug, adaptor or distribution board.

Mains supply
