BATTERIES

Battery must be replaced in a non-hazardous area only. Battery replacement is not an intrinsically safe operation. Use only approved battery. Failure to do so may result
in sickness or death.
Never alter or modify this instrument. Substitution of components may impair intrinsic safety. Repair or replace parts only with the M components approved for this
unit. Failure to do so may adversely affect product performance and result in sickness or death.
Only charge the instrument in non-hazardous areas using a M power supply. Do not use the 70 series detector in a potentially hazardous environment when it is
plugged in. Do not attempt to charge alkaline batteries. Failure to do so may adversely affect product performance and result in sickness or death.
Do not open the 70 series detector in a potentially hazardous area. Failure to do so may result in sickness or death.
CAUTION
Observe proper polarity when inserting the battery. Polarity is marked on the inside of the battery compartment.
This instrument contains a lithium battery. Dispose of battery in accordance with local regulations.
When re-assembling the unit, inspect the rubber gasket for damage and ensure it is seated properly between the front and back cover. Do not use the unit if any damage is observed.

Charging the Li-ion Battery

The state of battery charge is shown in the bottom right-hand corner of the instrument's LCD as bars within the battery symbol. The
unit also has a "LOW BATTERY" warning and a "LOW BATTERY" alarm to warn the user that recharging of the battery pack is required.
Recharging the unit's discharged Li-ion battery requires approximately  hours under normal temperature conditions (fast charge to
90% of capacity). A trickle charge continues once the fast charging period has been concluded, to fully utilize the battery capacity.
Charging batteries at temperatures less than 50 °F (10 °C) or greater than 86 °F (0 °C) may reduce battery run-time and/or battery
life. The 70 series detector cannot be operated during the charge cycle.
The following steps should be followed to properly recharge the instrument's Li-ion battery:
1. Turn off the unit. Plug the charger output into the receptacle near the bottom of the detector (Fig. ).
. Plug the supplied charger into a suitable electrical outlet. Output of the charger is rated at 1V DC 1000 mA.
. You will note moving bars within the battery symbol on the instrument's LCD, indicating that charging is occurring.
. Charging is complete when the LCD displays "CHARGING COMPLETE."

Replacing the Batteries

The unit may be operated with a Li-ion battery or with  approved AAA size alkaline batteries. Approved batteries are listed in Table . Only these batteries have been
evaluated to meet the requirements of intrinsic safety for CSA approval. Use of batteries other than those listed here may impair intrinsic safety.
