long periods. This will eliminate the possibility of battery acid leaking from the
batteries and corroding the transceiver.

! Do not use this device in or near a mining facility, which uses remotely trig-
gered explosives or in areas labeled “Blasting Area”. Premature or accidental
detonation may result.
