Power the radio
Note: No batteries are included with this radio.
Back up battery is to back up the preset stations and also clock functions during power outage, not
for formal radio operation. It is necessary to insert back up battery (2 x UM-3 1.5V, AA not supplied)
for memory back up even if you use AC power only. Without the backup battery, time and preset
station will get lost if you remove the AC power cord from AC outlet or during AC power failure.
Back up battery compartment is located below the main battery compartment. Insert 2 x AA size (UM-
3) battery and ensure the battery is inserted in accordance with the diagram shown.

1. Battery operation
Pull out the battery compartment locker to release battery compartment. Insert 6 x D size (UM-1)
battery into the compartment. Ensure the battery is inserted in accordance with the diagram
shown.
Return the battery locker to the original position. If the radio is not to be used for an extended
period of time, it is recommended that the batteries are removed from the radio.
Battery operation using alkaline batteries
●
1. Before you insert the batteries, if you use non-rechargeable batteries, make sure the NiMH/
Alkaline switch which is located inside the battery compartment is switched to Alkaline position.
If you use rechargeable batteries, make sure to switch NiMH/ Alkaline switch to NiMH position.
2. Reduced power, distortion and a “stuttering sound” are all signs that the batteries need
replacing.
● Battery operation using rechargeable batteries
1. Slide the battery switch to the NiHM position.
2. Insert 6 UM-1 (D) batteries into spaces in the compartment. Make sure all batteries are inserted
with the correct polarity as shown in the battery compartment. The radio is also designed to be
used with NiMH rechargeable batteries.
3. Make sure the radio is switched off and connected to an AC outlet . When the charge indicator
flashes green this indicates that the batteries are charging. Batteries will be fully charged in
about 10 hours. The battery charge indicator will show a steady green light when the battery
charging is complete.
Note:
Duration for charging your batteries fully can vary depending on the mAh capacity of a battery.
Higher mAh batteries require longer charging time.
Important:
Under some conditions the charging LED indicator may switch off after flashing briefly. This
may happen if the batteries are already freshly charged, or if the radio detects that you may be
attempting to recharge alkaline batteries or mixed different types or capacity of rechargeable
battery. In these cases the charging will be stopped.
2. AC Power operation
Before you plug the AC cord into the AC socket, be sure the voltage is correct. If you have
batteries in the radio and use the AC power cord, the batteries will automatically be disconnected.
The AC cable hook is designed to store the cord when the radio is not in use.
IMPORTANT:
The AC Cord is used as the means of connecting the radio to your power supply. The AC Cord
used for the radio must remain accessible during normal use. In order to disconnect the radio from
your main power supply completely, the AC Cord should be removed from your main power supply
completely.
3. Powered via DC IN socket
The radio can also be powered via the DC IN socket which can allow 12Volt DC. An additional
12Volt DC power adapter or DC power source not supplied for this device.
"This product is intended to be supplied by a Listed Power Adapter or DC power source, rated
12Vdc, 1.2A min. and Tma 35 degree C min., if need further assistance, please contact SANGEAN
for further information."
Note:
Never use the 12 Volt socket in rainy or moist conditions to prevent moisture from entering the
radio. Always keep the rubber covers well closed under these conditions.
