POWER SUPPLY
BATTERY OPERATION
1. Clock operation
• Open the lid of the battery compartment.
• Insert as indicated two UM3 (IEC LR6) alkaline batteries.
These batteries should always be fitted. They serve as
standby batteries for the clock and the station memory.
2. Radio operation
• Insert as indicated four UM2 (IEC LR14) alkaline batteries.
• Close the battery compartment lid.
Important
• Exhausted batteries should be removed from the set
immediately.
• If the set is not in use for long periods, the batteries should
be removed from the set even if they are new.
• No responsibility can be accepted for damage due to
leaking batteries.
NOTE ON ENVIRONMENTAL PROTECTION
Do not throw exhausted batteries in the household refuse.
Hand over the old batteries to your dealer or public collecting
points when buying new ones.
MAINS OPERATION
The unit is designed to operate from a mains supply of 230 -
240 V ~, 50/60 Hz
• Connect one plug of the mains lead to the MAINS socket
and the other plug to the wall socket..
- This will switch off the batteries in the battery compartment.
SETTING THE CLOCK TIME
As soon as the two standby batteries (UM3 batteries) are
inserted, the indication'SEC' flashes in the display and the
clock begins to run.
The clock time can be set with the unit switched on or off.
For setting:
• Press the TIME button and hold it pressed.
– The display shows'ADJ'.
• Now set the correct time with the DOWN/HOUR (hours)
button and with the UP/MINUTE (minutes) button.
A single press of the respective button advances the setting
by one hour or one minute respectively; if button is held
pressed, setting advance rapidly.
The minutes will not be carried over to the hours if, for
example, the minutes indication changes from 59 to 00.
RADIO OPERATION
• Switch on and off with the x ON/ w OFF switch
• Adjust the volume with the control E VOLUME.
•
The tone can be adjusted with the TONE LOW/HIGH control.
AERIALS
– The telescopic aerial is intended for receiving FM (VHF) and
SW (shortwave) stations.
• For FM reception the aerial should be fully extended, then
swivelled and rotated until best results are achieved.
• For SW reception the telescopic aerial should be vertical.
– For receiving MW and LW stations there is a ferrite rod
aerial inside the set.
• The best position for receiving a station should be found by
rotating the set about its vertical axis.
WAVEBANDS
• Select the waveband with the switch FM/MW/LW/SW.
The waveband selected is shown on the display.
On FM (VHF) and SW (shortwave) the frequency is shown
in MHz, and on MW (mediumwave) and LW (longwave) in
kHz.
FM 87.5 - 108 MHz
MW 531 - 1602 kHz
LW 153 - 281 kHz
SW 5.9 - 15.5 MHz (49 - 19 m)
Intermediate frequencies: FM 10.7 Mhz, AM 450 kHz.
SENSITIVITY SWITCH (SENS LOC/DX)
• Normally this switch should be set to the DX position =
remote stations.
• If the signal received is too strong (distortions), set the
switch to LOC = nearby stations.
The switch functions only on FM and SW reception.
TUNING TO STATIONS
• Select the waveband with the switch FM/MW/LW/SW.
• Start the station search with the UP/MINUTE button (in the
direction of higher frequencies) or with the DOWN/HOUR
button (in the direction of lower frequencies):
– Pressing briefly = tuning in steps,
– pressing longer = tuning automatically.
– The tuning steps are 50kHz in the case of FM, 9 kHz in
the case of MW, 1kHz in the case of LW and 5 kHz in
the case of SW.
• As a result of poor reception conditions during automatic
station search it may happen that the station received is not
optimally tuned in. In such instance briefly press the
UP/MINUTE or DOWN/HOUR button once or twice until
the station is correctly tuned in.
Note:
When the battery voltage decreases, the automatic station
search may function incorrectly. In this case, change the batteries.
