2.0 GENERAL
The CEECO Model MHW-341-D Magnetic Hookswitch Wall Telephone is
equipped with a magnetically operated hookswitch. The MHW-341-D is
designed for special applications where a telephone must be sturdy and attractive,
and automatically dial a single number. It is equipped with an ATD-11 automatic
tone dialer that will dial a single number of up to eleven (11) digits. When the
handset is lifted, the telephone will automatically dial the pre-programmed
number. The automatic dialing feature is activated by hookswitch closure. The
telephone is not necessarily designed for incoming calls, but can receive them. If
a call is received, the telephone will still automatically dial the programmed
number when the handset is lifted. This will have no bearing on the phone cal,
however, other than to briefly hear the digits dial out.

3.0 PROGRAMMING
NOTE: It is recommended that you ground yourself to prevent ESD
damage to the PCB(s). This can be done through the use of an
electrostatic bracelet or other such device. In the absence of any
such device, it might suffice to simply touch a conduit or other
grounded pipe or object to dissipate any built up static electricity.
3.1 Please refer to the diagram on the next page for mini-jumper location
and positioning. Programming is accomplished by position plastic
hardware mini-jumpers in the proper positions for the desired calling
pattern. The mini-jumpers are designed to bridge pairs of copper pins to
activate the desired dialing pattern.
3.2 Locate the ATD-11 Automatic Dialer.
3.3 If the number to be programmed is a (1+) call, position the J1 mini-jumper
on the "1+" position, bridging the left and center copper pins. This will
cause the digit "1" to be dialed in front of the other programmed digits. If
the number to be programmed is a local call, position the J1 mini-jumper
on the "B" position, bridging the center and right copper pins.
3.4 If a 3 digit area code is to be dialed, the J3 mini-jumper must be set to the
"11" position, bridging the center and left copper pins. If the number
being dialed does not require the area code, position the J3 mini-jumper on
the "8" position, bridging the center and right copper pins.
3.5 Set each mini-jumpers on the A-K matrix board to correspond to the digits
of the number to be dialed. Beginning with column “A” at the top,
position the plastic mini-jumper to bridge the pair of copper pins
correspond to the desired digit (1-0). Proceed in the same manner, from
left to right, until all desired digits are programmed. Do not skip any
columns, as the digits must be represented in an unbroken string. Any
unused mini-jumpers must be removed from the board to ensure proper
dialing. Do not discard the unused jumpers, as they may be needed for
future use. It is recommended that they be taped or otherwise secured
somewhere nearby, within the device.
3.6 Be sure each mini-jumper is properly positioned to make good contact and
dial the intended number.

PROGRAMMING CONTINUED…
3.7 In most installations, the J2 mini-jumper will remain in the “1” position,
bridging the center and left copper pins. If dial tone delivery is delayed by
more than one second; however, then J2 will have to be set in the “3”
position. A simple test would be as follows: with the telephone line cord
connected to the intended telephone line, temporarily remove the J2 mini-
jumper. As accurately as possible, measure the time delay between the
moment the handset is lifted and the moment the phone receives dial tone.
Try it several times. If this time is consistently 1 second or less, position
the J2 jumper on the "1" position. Otherwise position the J2 jumper on the
"3" position to set the delay before dialing to 3 to 4 seconds.
3.8 Programming is now complete and the telephone is ready for installation.
It is highly recommended to read section 6.0 at this point and pre-test the
phone, prior to actual installation.

5.0 INSTALLATION NOTES AND ASSEMBLY INSTRUCTIONS
5.1 Using a 301-037 security tool (sold separately), loosen (do not remove)
the locking screw on the rear of the phone. The security tool is for a
standard 5/32" button head screw, generally used on the framework of the
phone booths.
5.2 Separate the cover assembly from the backplate assembly by pulling the
bottom forward and lifting up. The backplate assembly is designed rest on
any flat vertical surface.
5.3 Run the inside station wire into the enclosure and terminate on the RJ11C
terminal block inside. As depicted on the following page. The CEECO
provided terminal block (jack) must be used, as it contains required over-
voltage protection circuitry.
5.4 The use of a gas tube station protector is recommended. The station
ground should not exceed 50 ohms.
5.5 Plug the modular line cord from the cover assembly into the RJ11C
terminal block.
5.6 Dress the line cable away from the locking screw and install the cover
assembly by placing the two tabs into the two corresponding slots and
pushing forward until the housing slips into place for the security screw.
5.7 Secure the cover assembly by tightening the security screw on the rear of
the case.
*****WARNING*****
A. Never install telephone wiring during a lightning storm.
B. Never install telephone jacks in wet locations unless the jack
is specifically designed for wet locations.
C. Never touch uninsulated telephone wires or terminals
unless the telephone line has been disconnected at the
network interface.
D. Use caution when installing or modifying telephone lines.

6.0 TESTING
6.1 With the phone connected to a working telephone line, lift the handset.
Dial tone should be heard and the pre-programmed number should
automatically dial out.
6.2 The microphone is muted while the phone is dialing. Normal phone
operation should follow when the call is answered.
6.3 When the call is complete, hang up the phone.
6.4 Place a call to the phone.
6.5 The phone should ring indicating the incoming call. Answer the phone,
tones will be heard as the phone briefly dials out the pre-programmed
number, and normal phone operation should follow.
6.6 Hang up the phone. It is ready for use. If any problems were experienced,
please refer back to section 3.0 and otherwise to section 10.2.
