inside the compartment. The connector only
fits on the battery one way.

ies can leak chemicals that can destroy elec-
tronic parts.

craftsmanship. The following suggestions will help
you care for your TRC-512 so you can enjoy it for
years.
Keep the TRC-512 dry. If it gets wet,
wipe it dry immediately. Liquids might

wear of parts.
Handle the TRC-512 gently and care-
fully. Dropping it can damage circuit
boards and cases and can cause the
