Do not store this equipment in:
• Direct sunshine, near heating devices or in an automobile in the summer time.
• Locations with high humidity and poor ventilation.
• Dusty or smoky environments.
• Extremely low temperature.
Handling

Service or perform adjustments.
• Do not apply great force to the keys and switches.
Be sure the slide switch inside the battery cover is set to the right Position, If alkaline
batteries are used set the switch to right (dry position). If NiCd batteries are being used set
the switch to the left (NiCd position)
Warning: If the switch is in the NiCd position when alkaline batteries are used may cause
these batteries to over heat, explore or leak.
Antenna
Due to the broad applications of this unit, the supplied antenna is for the 800MHz cellular band.
It may be necessary to use a different antenna more appropriate for your application.
The receiving conditions vary with location and antenna. On some occasions, it’s not possible to
receive the desired signals due to strong Interference from other electronic sources such as
broadcast stations.
Connecting to other devices
When connecting this unit to other devices (CATV cable etc) be sure that the measured
system voltage is not greater than the maximum input voltage. Use attenuators to prevent
the input voltage from being overloaded by higher than the rated input voltage(5V rms).
If the input voltage is greater than the rated input voltage of this unit, possible damage may
result.
