ALARM

The TC-540 cordless handset operates like any other

telephone handset. You can

use it in the yard, at the pool,

at the mailbox, or any place

within the operating range of

the base unit. If you move out

of the base unit’s operating

range, you will hear a warning

tone. Move closer to the base

unit to deactivate the alarm. If you remain out of range for too long, the TC-540 will disconnect from the line.

If the handset loses its

security code you will also hear an alarm tone. To reset this security code place the handset in the base unit for a few seconds. Pick up the handset and try your call again.

Interference from other appliances may also cause the alarm to sound. To prevent interference, move the base unit to another location and fully extend the base unit antenna.

STANDBY MODE

When the handset is in the TALK mode and is returned to the base unit, it will automatically return to the “Standby” mode and disconnect the call. It is not necessary to press TALK to disconnect the call. In the “Standby Mode” the INDICATORS will not be lit.
