2) Adjustment Mode
The DJ-195 does not require a serviceperson to manipulate the components
on the printed-circuit board, except the trimmer when adjusting reference fre-
quency and deviation.Most of the adjustments for the transceiver are made by
using the keys on it while the unit is in the adjustment mode.Because the ad-
justment mode temporarily uses the channels, frequency must be set on each
channel before adjustments can be made.For instructions on how to program
the channels, see the “DJ-195 INSTRUCTION MANUAL” which came with the
product.In consideration of the radio environment, the frequency on each chan-
nel must be near the value (+/-1MHz) listed in the table below.To enter the
adjustment mode, set key lock and input 490217.Decimal point at 100MHz and
10MHz appears in LCD. (To release the mode, set key-lock and input 490217.)
