which user is assigned.
Some handset information and settings are available 
using a series of menus from the handset. Other 
settings can optionally be made using the handset 
keys directly.

cannot successfully access the option, it may be 
because the tones transmitted from your handset are 
too short to be recognized.
Should this happen, you can increase the length of 
the transmitted tones for the duration of the current

Monitor handset This handset is placed in the baby’s room to monitor 
and transmit sounds in the room to a speaker 
handset. The monitor handset places a call to the 
speaker handset. From the monitor handset, you can 
change the BabyPhone call number—the number of 
the handset you use to listen to the monitor.
When this feature is activated, the monitor handset 
automatically calls the speaker handset. The monitor 
handset mutes the ringer and earpiece so the baby is 
not disturbed. All keys on the monitor handset are

Using Direct Call
Direct call is a feature that lets you program the 
handset to dial a set number regardless of which key 
is pressed. Direct call can be activated with any key 
on the keypad.
This feature is useful if there is a number that you 
call repeatedly, or if you want to program the phone 
for a child to contact you easily while you are out.
Storing a number in the direct call option and 
activating the option configures the handset to 
automatically ring the number by touching any key 
on the handset. This means that if any key is 
pressed, for example, by a small child, the same 
direct call number is always dialed. 
Pressing any key again will end the call.
NOTE: Only one direct
call can be stored at a
time. When this feature
is on, no other outgoing
calls can be made,
though calls can still be
received.
When turning off the direct call feature, do the steps 
quickly to prevent the direct call number from 
dialing.
To store a direct call:
1. Press  to access the menu.
2. Select >Handset>DirectCall and press . 
Enable Direct Call? displays.
3. Press   to confirm. DirectC.No is displayed. 
4. Enter the number to be called. 
5. If a direct call number has been set before, it will 
show on the display. To change the displayed 
number, press   until the old number is 
removed, then enter the new number.
6. Press   to confirm the direct call function.

Using Direct Call
Direct call is a feature that lets you program the 
handset to dial a set number regardless of which key 
is pressed. Direct call can be activated with any key 
on the keypad.
This feature is useful if there is a number that you 
call repeatedly, or if you want to program the phone 
for a child to contact you easily while you are out.
Storing a number in the direct call option and 
activating the option configures the handset to 
automatically ring the number by touching any key 
on the handset. This means that if any key is 
pressed, for example, by a small child, the same 
direct call number is always dialed. 
Pressing any key again will end the call.
NOTE: Only one direct
call can be stored at a
time. When this feature
is on, no other outgoing
calls can be made,
though calls can still be
received.
When turning off the direct call feature, do the steps 
quickly to prevent the direct call number from 
dialing.
To store a direct call:
