1.7 Radian IS Usage Cautions
CAUTION
• This device incorporates circuitry to absorb most static
discharges. However, severe static shock may cause inaccurate
operation of the unit. Use anti-static precautions where possible.
• This device is a precision instrument. Although it is designed
for rugged operating conditions, it performs best when handled
with care.
• When the access cover for Radian IS is closed and latched, and
the port covers are closed, the enclosure is sealed to provide
protection against adverse environmental conditions. To
minimize the possibility of damage, always keep the access
door closed and latched except when exchanging data cards or
batteries and keep the ports covered except when in use.
• Do not eject the data card while the Radian IS is logging data, or
you may lose part of, or your entire, data file.
• The Radian IS can accept an input supply voltage in the range
+9 to +18 V DC. This may not be the same range as other Sokkia
products with which you are familiar. Do not operate the
Radian IS outside the specified voltage range.
• Drawing more than the specified maximum current (1 amp
combined total) from the two COM ports will cause an internal
fuse to interrupt the current. If this happens, immediately
reduce the load and allow the unit to automatically reset its
protection circuitry.
• We recommend that you do not use the Radian IS on a moving
vehicle.
