NOTE Cautions when using the connector
1. Be sure to connect the specified male connector for this connector.
Prepare the cable and the connector connected with an external device
at your side.
2. Be sure to connect according to the pin arrangement shown in the
previous page. Wrong connection will cause damage to the
instrument.
3. When the connector is used as a power source connector:
• Supply power such as a battery (which is prepared by you) to pin
No.3 (power terminal) and No.5 (ground terminal). This enables the
instrument to activate by the external power source though the
carrying-handle battery BC-80 has been mounted on it.
• Used the power within the range specified below.
Rated Input: 7.2 - 11V
Using without this range will result in damage to the instrument.
4. When the connector is used as a communication connector:
• Connect RS-232C signal from PC to pin No.1 (input terminal) and
No.2 (output terminal). This enables the instrument to communicate
with an external device.
5. Use this connector at your own responsibility except the case shown
in the SYSTEM DIAGRAM on p.6-1.
