11) If the optical connector connected to the optical input connector is
damaged, dirty, or otherwise compromised, the instrument will be
unable to perform as expected. At worst, this may cause damage
to the instrument’s optical connector.
12) When attaching the optical connector, take care not to damage
the optical input end.
13) If the optical input end or connector is soiled with dirt or grime,
clean the end with specialized optical connector cleaner.
14) When not using the instrument, attach the optical connector cap to
protect the connector from dirt, grime, and other foreign particles.
15) To prevent damage when attaching or removing the optical input
connector cap, do so carefully so as not to rub or apply pressure to
the connector with the cap.
9-2 Precautions When Using the Batteries
1) If the plus or minus terminal of the battery holder is dirty, contact
with the battery will be weakened, possibly causing the power to
cut out. If dirty, wipe the plus and minus terminals clean with a
dry cloth.
2) Do not allow the batteries to come into contact with water (including
rain water and sea water). Also, do not apply strong physical
shocks.
3) Shorting the plus and minus terminals of the batteries with metal or
other conductive objects causes a large current to flow that can
damage the batteries and emit heat. Take care not to short the
terminals when handling the batteries.
4) Disassembling the batteries or placing them in fire is extremely
dangerous and must never be attempted.
5) Do not discard spent batteries together with general household
waste (unless your local laws permit doing so).
6) Check the polarity/orientation of the batteries carefully before
inserting them into the battery holder. Incorrectly oriented
batteries can result in damage to the instrument.
7) Remove the batteries during periods of extended non-use.
Leakage from batteries can occur, resulting in damage to the
instrument.
8) The instrument does not perform battery recharging. Please use
a separate, dedicated charger for nickel metal-hydride rechargable
batteries.
9) Always operate the instrument in a way that is appropriate for the
type of batteries you are using.
