ADDITIONAL OPERATING TIPS If the handset is moved to a point where the base and handset can no longer communicate, the handset will make a quick series of beeps to signal Out of Range. OUT OF RANGE WHEN PHONE IS ON If you are presently engaged in a phone conversation move closer to the base. If the base unit does not communicate with the handset within 25 seconds of losing contact, it will automatically hang up. OUT OF RANGE WHEN PHONE IS OFF If the phone is OFF, the handset and base still monitor each other to make sure that they can communicate. If the handset is moved out of range, the handset will make a series of beeps, and then the PHONE and MUTE/ LO.BATT LEDS will flash continually. The handset will re-link with the base automatically once it is brought back within range. The unit will then be able to receive and place calls. When the base unit is unplugged from the power supply, the handset will give the Out of Range warning beep. Plug the base in again and this will stop. NOISE OR INTERFERENCE Your VTech VT1901 cordless telephone has auto-channel scan circuitry which will detect excess noise and change the channel of the phone to reduce it. This is done automatically. Since the VTech VT1901 is a fully digital phone, it does not suffer from noise associated with regular cordless phones. At times you may experience occasional "drop outs", especially at the extreme edges of the phone's range. Simply move closer to the base unit and this will disappear. AUTOMATIC SECURITY CODING Your VTech VT1901 phone is programmed with a digital security code, which is factory set from 16.8 million possible codes. This unique security code allows your handset and base to recognize each other, and minimizes the possibility of another cordless phone using your telephone line. 1901MANUAL 27 27 1/28/99, 3:30 PM
