supplied adhesive tape, secure the antenna to a nearby wall or window,
depending on where you get maximum range. Do not secure this
antenna to metal.
3. Regular car AM radio antennas are convenient, and generally offer
sufficient range. Just plug the antenna's plug into the transmitter's
“ANTENNA” jack.
Tuning the antenna for maximum range
The transmitter should be adjusted with a field strength meter to get the
strongest signal for its antenna. These meters can be purchased from most
electronic component shops. Or contact SECO-LARM (model X-PDC2).
1. Connect the antenna, and turn the field strength meter ON. Apply power
to the transmitter, and trigger it with the manual page button or any zone.
2. Tune L1 to get maximum power reading.
3. Then tune C1 to get maximum power reading.
4. Then tune C2 to get maximum power reading.
5. Fine tune by repeating steps 2, 3, and 4.

PAGING VIA PANEL POSITIVE OR NEGATIVE OUTPUT
(VIA BURGLAR ALARM SIREN/BELL OUTPUT)
NOTE:
1. This method is most suitable for the SECOPAGE 35E, but will also work
for the SECOPAGE 35E7. Only the red and black wires, plus the blue or
purple wires, are used. (For the SECOPAGE 35E7 only, the yellow wire
must be grounded.)
2. Use only if the alarm outputs an N.O. positive (+) or negative (—) siren/
bell signal for a minimum of at least 1 second.
3. The blue and purple wires draw only a few mA of current.
4. Pager requires 1A of power during transmission.
5. The manual page button operates normally.
6. NOTE the pager is connected to power 24 hours per day.
7. ANTENNA MUST BE CONNECTED.

TRANSMISSION RANGE TEST
One person should trigger the pager while another is in a house, office, or
wherever the page signal should reach. This will assure that the user will
receive a signal for his/her particular application.
Press the ON/OFF button each time the receiver beeps. This returns the
receiver to the standby state, ready to receive the next page signal.
Maximum range is up to 2 miles. However, range can vary depending on
terrain, environmental conditions, type of antenna used, and so on.
When using the pager inside a building (especially a high-rise), keep the
receiver near a window or a telephone to help increase the effective range.
NOTE — For the transmission range test, stand at least 3 feet (1 meter)
away from the transmitter. Otherwise, you may experience erratic
operation.

insulate the unused wires.
