Automatic clock setting
When switched on your clock radio will receive and synchronise to one of the most accurate clocks in the world. The signal is received from the official
UK standard frequency and time signal transmitter (MSF) located at Rugby in the U.K.
At certain times of the year the MSF transmitter closes down for maintenance during this time it will be necessary to set the clock manually (see the
sections headed Setting the Time and Date Manually). Recorded information on transmitter status can be obtained on 020 8943 6493.
Your clock radio will automatically synchronise with the MSF time signal when the transmitter is switched back on. The time setting or synchronisation
takes 2 to 3 minutes to complete if the reception of the radio time signal is undisturbed. This process will take longer if the time signal level is very weak
(e.g. in locations that are a long distance from the MSF transmitter) or if it is subject to interference from thunderstorms, nearby TV sets, computers or
household appliances that are not suppressed, etc. In general your clock radio will receive the time signal at any place where a radio is able to receive
Long Wave broadcast programmes well.
Switching on
1. Place the unit on a flat surface. Plug the mains lead into a wall socket
and switch on.
2. The built in microprocessor will automatically activate the Radio
Controlled clock and initiate a search for the time signal. When first
connected to the mains supply the MSF signal indicator shows the
MSF signal level.
3. Rotate your clock radio or change its position until the highest signal
level is obtained.
4. It is recommended that your clock radio is placed as far away as
possible from any sources of interference such as computers or
televisions, etc.
5. When your clock radio is receiving the radio time signal, the seconds
digits will appear in the display and the colon will flash once every
second in time with the radio time signal. When the time setting
process has been completed, the exact time and day of the week will
appear in the display. The MSF signal indicator becomes the Day
of week indicator after initial time setting has taken place.

General
Do not allow this unit to be exposed to water or steam. 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 or LW bands.
Mains supply
The CR9910 will operate from a supply of AC 230volts, 50Hz only.
For your convenience this product is supplied with a plug which is fitted with
a fuse of the appropriate rating. If the plug supplied is not suitable for your
socket outlet, it should be removed by unscrewing the plug top, the terminal
screws, and removing the cable.
The correct style of plug to suit your household together with a correctly
rated fuse should be fitted.
IF IN DOUBT - CONSULT A QUALIFIED ELECTRICIAN
IMPORTANT. DO NOT make any connection to the larger terminal which
is marked with the letter E or by the safety earth symbol or coloured
Green or Green-and-yellow.
The wires in the mains lead are coloured in accordance with the following
codes :-
BLUE - NEUTRAL BROWN - LIVE
As these colours may not correspond with the coloured markings identifying
the terminals in your plug, proceed as follows:-
The wire coloured BLUE must be
connected to the terminal marked N
or coloured BLACK.
The wire coloured BROWN must be
connected to the terminal marked L
or coloured RED.

Fuse
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.
IF IN DOUBT - CONSULT A QUALIFIED ELECTRICIAN.
Back-up Battery (not necessary for the unit to function)
Slide the battery cover catch in the direction of the arrow. Remove the
battery cover. Fit a 9 volt IEC size 6LR61 (6F22, PP3) or equivalent battery
into the compartment. Replace the battery cover.
The time and alarm settings will be retained during a temporary failure of the
AC mains supply. The LED display will not be operational but the Radio and
buzzer alarms will continue to operate at their preset times.
If your clock radio is not to be used for a prolonged period of time, remove
the battery to avoid damage by battery leakage.
