NOTE
If the transmitter searches the Field Wireless
Network for long time at low ambient
temperature condition, sometimes error “AL.70
LOWBAT” is displayed on the Integral Indicator.
Even though using new batteries, it can occur. It
occurs because of battery characteristics. After
joining to the Field Wireless Network, this error
will be cleared within one hour if battery has no
failure.
