Handset Hook
When the cordless voice terminal is wall mounted, the handset hook
allows the handset to be securely placed into the base unit.
Directory Card
The directory card is provided so that you can write the Intercom
(ICOM) Number/Personal Dialing Code (PDC) assigned to the cord-
less voice terminal and the ICOM No./PDC and names of other peo-
ple on the system. When you have more than one MLC-5 Cordless
Voice Terminal in an area, it is especially important to write the ICOM
No./PDC assigned to each of them to help ensure that the proper
handsets are always placed into their correct base units.
Battery Contacts
Batteries begin recharging when the battery contacts on the handset
touch the contacts on the base unit. Periodic cleaning of the con-
tacts using a soft eraser may be necessary.
Channel Indicator
The channel indicator lights to identify which channel is currently
being used or being programmed. A “P” is displayed when the cord-
less voice terminal is in programming mode.
Mode
There are three modes of operation:
The Charge light comes on whenever the handset is properly
placed in the base unit and indicates that the batteries are being
recharged.
The Talk light comes on whenever the handset is removed from
the base unit and is turned on with the On/Off button.
The Program light comes on when the T/P switch is set to P for
programming mode.
T/P Switch
The T/P switch is used to test the voice terminal and to program
channels and features.
Ringer Vol
The ringer volume switch adjusts the volume of the base unit ringer.
Slide it to the right (increases loudness) or to the left (decreases
loudness) to adjust the level. The handset ringer volume cannot be
changed.
Message
The message light goes on steady whenever there is a message for
you.

Flexible Antenna (packaged separately)
This antenna can replace the retractable antenna so that the
handset is easier to carry when placed in the carrying adapter.
On/Off
The light next to this button must be on when you answer or make a
call. Two beeps sound if the handset is out of range and must be
moved closer to the base unit.
Message
When the light is on next to this button, there is a message for you.
The light blinks after 20 seconds to conserve battery power.
Lo Batt
This light blinks and a tone sounds when the batteries have fewer
than 15 minutes of use remaining.
Line Card Label
The line card label next to the blank buttons can be marked with a
ballpoint pen, not a pencil, to indicate which features or lines are
assigned to the corresponding button. If you need to make correc-
tions or updates, you can erase the label, but do not remove it.
Line/Feature Buttons
For MERLIN Systems, of these five programmable buttons, four are
initially reserved for outside lines and one, located to the left of
On/Off, is an intercom line. Any of the four outside line buttons can
be programmed with MERLIN System features.
For System 25, of the five programmable buttons, the last two on the
bottom row are System Access buttons reserved for making and
receiving calls. Any of the three remaining buttons can be pro-
grammed with System 25 features.
Status
In order to conserve battery power, the lights on the handset (except
On/Off) go off in 20 seconds. When this button is pressed the indica-
tor lights relight to reflect the current status of calls and features. If
the handset is out of range when Status is pressed, you hear two
short beeps that indicate the handset must be moved closer to the
base unit.
Trans
Press this button when you want to transfer a call to another number.
Hold

When the cordless voice terminal is in programming mode, press this
button to program channel selection.
12 Number Card
This card should be removed, labeled with the ICOM No./PDC
assigned to the cordless voice terminal, then replaced. This is espe-
cially important when you have more than one cordless voice termi-
nal in an area to ensure that the handset is always placed into the
correct base unit.
13 Battery Contacts
Batteries begin recharging when the battery contacts on the handset
touch the contacts on the base unit. Periodic cleaning of the contacts
using a soft eraser may be necessary.
