• Do not allow metallic or foreign objects to enter the device through connectors or
any other openings. Otherwise, a malfunction or electric shock may result.
Electrical Warnings
• Before operating this instrument using mains electricity, you must connect the
protective earth terminal of the instrument to the protective conductor (mains) of
the power cord. The mains plug shall only be inserted into a socket outlet
provided with a protective earth contact. Never negate the protective action by
using an extension cord (power cable) without a protective conductor
(grounding).
• If there is any possibility that the ground protection could be impaired, you must
make the instrument inoperative and secure it against any unintended operation.
• The instrument must only be connected to a power source corresponding to the
type indicated on the rating label.
If an unauthorized power supply cord is used to power the instrument or charge the
batteries, Olympus cannot guarantee the electrical safety of the equipment.
Battery Precautions
• Before disposing of a battery, check your local laws, rules, and regulations, and
follow them accordingly.
• Transportation of lithium-ion batteries is regulated by the United Nations under

Maritime Organization (IMO), the US Department of Transportation (USDOT),
Transport Canada (TC), and others. Please contact the transporter and confirm
current regulations before transportation of lithium-ion batteries.
• Do not open, crush, or perforate batteries; doing so could cause injury.
• Do not incinerate batteries. Keep batteries away from fire and other sources of
extreme heat. Exposing batteries to extreme heat (over 80 °C) could result in an
explosion or personal injury.
• Do not drop, hit, or otherwise abuse a battery, as doing so could expose the cell
contents, which are corrosive and explosive.
• Do not short-circuit the battery terminals. A short circuit could cause injury and
severe damage to a battery making it unusable.
• Do not expose a battery to moisture or rain; doing so could cause an electric
shock.
• Only use the 38DL PLUS unit or an external charger approved by Olympus to
charge the batteries.
• Only use batteries supplied by Olympus.
• Do not store batteries that have less than 40 % remaining charge. Recharge
batteries to between 40 % and 80 % capacity before storing them.
• During storage, keep the battery charge between 40 % and 80 %.
• Do not leave batteries in the 38DL PLUS unit during instrument storage.
