•Do not attempt to charge alkaline batteries. Non- rechargeable batteries can get hot or explode if you try to recharge them.

•Never install non-rechargeable batteries when RECHARGE ON/OFF is set to ON. Non- rechargeable batteries can get hot or explode if you try to recharge them.

•Dispose of old batteries promptly and properly. Do not burn or bury them.

."%#76+10".

You must use a Class ! 2 power source that

supplies regulated 9V

DC and delivers at least 400 mA. Its center tip must be set to positive and its plug must fit the intercom's DC 9V jack. Using an adapter that does not meet these specifications could damage the intercoms or the adapter.

•Use only fresh batteries of the required size and recommended type.

•Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

•If you do not plan to use the intercoms with batteries for a month or more, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

•Always connect the AC adapters to the intercoms before you connect them to AC power. When you finish, disconnect the adapters from AC power before you disconnect them from the intercoms.

•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

•Consult your local RadioShack store or an experienced radio/TV technician for help.

•If you cannot eliminate the interference, the FCC requires that you stop using your intercoms.

Changes or modifications not expressly approved by RadioShack may cause interference and void the user’s authority to operate the equipment.

You can power your intercoms using four AA alkaline or rechargeable nickel-cadmium (Ni-Cd)/nickel-metal hydride (Ni-MH) batteries (not supplied). For the best performance

and longest life, we recommend RadioShack batteries.

Rý.

1.Slide the battery compartment cover on the back of the intercom in the direction of the arrow to remove it.

2.Slide RECHARGE ON/OFF to OFF (if you are installing alkaline batteries) or ON (if you are installing Ni-Cd or Ni-MH rechargeable batteries).

3.Place the batteries in the compartment as indicated by the polarity symbols (+ and –) marked inside.

4.Replace the cover.

Once each intercom has been turned on and you connect its supplied AC adapter (see “Using AC Power”), rechargeable batteries (if installed) are automatically charged while the intercom is transmitting and standing by. The battery life for rechargeable batteries (Ni-MH, 1500mA) is about 37 hours.

When POWER/BATT LOW flashes or the intercoms stop operating properly, replace or recharge the batteries. Rý.
