This device is constructed of precision electronic components and should
never be disassembled.
. Do not store or use this device near heaters or in any area subject to ex-
cessive humidity or dust.
. Never allow water, condensation or metal objects to enter inside of this
device. Should anything ever enter inside, immediately switch power OFF,
and contact your retailer or a nearby dealer.
. Use only the CHA-2 battery charger to charge the power supply.
. Avoid overloading outlets. This is not only dangerous, it may also effect the
operation of this device.
. Always switch power OFF when not in use. Unplug the charger for extended
periods of non-use.
. Using in the vicinity of radio or TV receivers may interfere with the receiver's
signal.
. Never use thinner, benzine or other volatile agents for cleaning. Use only
a soft cloth dampened with a mild neutral detergent solution. Dip the cloth
in the solution and wring out until almost dry.
. Connect only equipment specified by the manufacturer (except for tape
recorder and computer with Centronics standard interface). The manufac-
turer assumes no responsibility for any damage or abnormal operation caus-
ed by use of non-specified equipment.
. Touching the connector may damage internal circuitry or result in poor
connection.
. The internal mechanism of the printer is precisely adjusted. Never touch the
moving element.
. Never interfere with the roll paper during printer operation. Doing so may
result in irregular printout.
. Use only the roll paper specified by the manufacturer. The manufacturer
assumes no responsibility for any damage or abnormal operation caused by
use of other types of paper.
. Frequent errors during data read and write operations may indicate a dirty
tape recorder head. Clean the tape head following the procedures specified
by the recorder manufacturer.
. Data read and write operations cannot be performed during printer opera-
tion. Confirm that printing is complete before data read or write.
The printer will automatically cease operation when the head is stopped by
paper jams, etc. In this case, correct the problem and then switch power
back ON to resume normal operation.
Always check the manual carefully to ensure proper operational procedures
before assuming malfunction.
