7 OPTIONS
Tron VHF can be supplied with the following equipment as options or spare parts.
In order to protect the radio from mechanical wear and tear, we recommend using
the leather carrier case with shoulder strap. If Tron VHF is used for on-board
communication, a battery charger and re-chargeable batteries are available specifi-
cally for this application. Other types of accessories are also available from
JOTRON’s agents.
