Security System
Your cordless telephone uses a digital coding security system to prevent
unauthorized use of your telephone line by another nearby cordless telephone.
The system has its own identifying signal created by microcomputers in both the
BASE UNIT and the HANDSET.

This telephone has an internal security code with 65,536 possible combinations.
Resetting Security Code and Channel Information
Communication between the HANDSET and the BASE UNIT may not be possible in
any of the following situations:
1. After a power failure.
2. After relocating the BASE UNIT by disconnecting the AC ADAPTOR.
3. After replacing the HANDSET BATTERY PACK.
To reset, place the HANDSET on the BASE UNIT for 2 to 5 seconds.
Multi-Channel Access
Your cordless telephone lets you select a channel from the 40 frequencies
available to transmit signals between the BASE UNIT and the HANDSET. When you
notice interference from other cordless telephones, change to another channel by
pressing the CH (CHANNEL) button on the HANDSET.
