ADJUSTMENT
The DTMF tone deviation has been adjusted at the factory, so does not normally need
to be adjusted.
•
DTMF tone deviation adjustment (for KMCl8/l8A)
1. Remove the three screws securing the back
of the KMC-18/l8A case, then remove the
back.
2. Connect the deviation meter to the
transceiver to be used, then connect the
KMC-18/l8A to the transceiver.
3. Hold down key [§J. The transceiver transmits
the DTMF tone corresponding to key &].
With key [§J still down, adjust semi-fixed
resistor VR 1 on the KMC-18/l8A board to set
the deviation to 2.2 kHz.
4. Put the back of the case on.
•
The KMC-18A allows you to adjust the deviation
using the single tone transmission function.
Perform steps 1 and 2 above, then put the KMCl8A into set-up mode. (To enter set-up mode,
hold down keys [JJ, [3], and
and switch the
power on.)
I*l
Next, press keys [ill, [Q], and
then press the following keys:

Adjust VRl while each tone is being transmitted,
setting the deviation to 1 kHz for the Row 1 tone
(key OJ) and to 1.5 kHz for the Column 1 tone
(key [[i).
