Warnings and Precautions

Please read these instructions carefully before putting the new terminal into

Before plugging in the terminal, make sure that the voltage stated on the terminal's
label matches the local power supply voltage. If this is not the case, do not
connect the terminal under any circumstances.
Although the IND780 is ruggedly constructed, it is nevertheless a precision
instrument. Use care in handling and installing the terminal.

Operating Environment

When selecting a location:
• Choose a stable, vibration-free surface
• Ensure there are no excessive fluctuations in temperature and no direct
exposure to sunlight
• Avoid drafts (for example, from fans or air conditioning)
• Readjust (calibrate) the terminal after any major change of geographical
position

Temperature and Humidity

The IND780 can be operated at temperatures and relative humidity conditions as
listed under Operating Environment in Table 1-1. The terminal can be stored at
temperatures ranging from –40° to 60° C (–40° to 140° F) at 10 to 95% relative
humidity, non-condensing.
