AC ADAPTER OPERATION
1. Insert the AC plug which is at the end of adapter cord into the AC ~ 6V input jack of the
product.
2. Plug the AC adapter into an AC power outlet. Only use the supplied AC adapter and
make sure the local voltage corresponds to adapter’s required AC input voltage.
3. As soon as you insert the power plug into the wall outlet, the display time will ash and
show . (Assuming there is no battery for backup or battery is weak). Please see
below how to set the correct time.
POWER FAILURE
If power failure occurs, the unit will switch off. As soon as the power supply returns,
will ash and display, indicating that you must reset the correct time before normal
operation.
BATTERY BACK-UP SYSTEM
1. Open the battery compartment cover by removing the
screw, then slide the battery cover out.
2. Insert 2 “AA” or LR6 sized batteries (3V) into the battery
compartment. In the event of a power failure, the batteries
will provide sufcient power to maintain the time. When AC
power is restored, the correct time will be restored and will
not require resetting.
• Neither the display nor the unit will operate until the unit is connected to an AC
outlet. BATTERY WILL ONLY RESTORE CLOCK SETTINGS WHEN AC POWER IS
RESTORED.
• Replace the battery once per year. The service of the battery depends on how often
and for how long the power supply fails. This varies from one region to another.
Note:
1. Always check the time and reset if necessary the rst time connecting the AC adapter
or after a power failure.
2. The 2 batteries are used for backing up the time in case of AC mains power failure,
under this circumstance, do not attempt to operate the unit, otherwise, battery service
life will be reduced.
BATTERY PRECAUTIONS
Follow these precautions when using batteries in this device:
1. The batteries (battery pack or batteries installed) should not be exposed excessive to
heat such as sunshine, re or the like.
2. Do not attempt to recharge, short-circuit, disassemble, heat or throw the batteries into
a re.
3. Do not mix old and new batteries.
4. Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel cadmium)
batteries.
5. If the device is not to be used for a long period of time, remove the batteries to prevent
damage or injury from possible battery leakage.
6. Do not try to recharge batteries not intended to be recharged; they can overheat and
rupture. (Follow battery manufacturer’s directions.)
7. Dispose of batteries properly in accordance with local laws.
