horizontally toward the sky on the rear cowling
by two-sided tape or hook & loop fastener.
Installation for car
Attach the GPS receiver’s top side with logo horizontally toward the sky on the
dashboard by two-sided tape or hook & loop fastener. Some kinds of windscreens
including heat-reflecting glass would be difficult to acquire the GPS satellite. In
that case, please attach on the roof.
Caution for installation
- To avoid the noise from the engine ignition, put the receiver away from the
engine, and do not fix the GPS receiver's cable together with other sensors'
cables.
- If the GPS receiver is subjected to strong vibration, malfunction may occur.
Place low-repulsion urethane (sponge or similar) around the sensor to absorb
vibration.
- If using the GPS receiver in the rain, wrap it with plastic bags so as not the
receiver and cables wet.

NOTICE POINTS
COLD START:
The first start after purchasing the GPS receiver, or the start after remaining
unused for a long period.
Please notice COLD START will take longer time to acquire the GPS satellite, like
about 35 seconds.
Turn on the power of the device 15-30 minutes before driviing in a open place to the
sky.
Please notice that aquiring the GPS satellite would be difficult in the following place;
- In doors or behind a building
- Between tall buildings
- Near the object that generates magnetism like high-voltage electrical power lines
- On the narrow road between dense trees or buildings
- When operating the GPS receiver through heat reflecting glass
To acquire the GPS satellite properly
- Acquire the GPS satellite in a open place to the sky.
- Keep the receiver’s top side with logo horizontally toward the sky.
- Do not move the place 15 to 30 minutes until completing the acquisition.
