1.8 Explosions
This unit has not been designed to be explosion-proof, and therefore it must not be used in
rooms or environments where there is a risk of explosion, nor in the presence of inflammable
anaesthetic products nor concentrated oxygen.
FIRE OR EXPLOSION HAZARD: Do not use the unit when inflammable or anaesthetic
gases are present.
1.9 Batteries
In this section the considerations to be taken into account for correct battery maintenance are
explained, as well as the process for changing it. Good battery maintenance optimizes its
duration, and guarantees that the that the device provides accurate indication about battery
charge.
The REANIBEX Serie 700 uses high capacity rechargeable NiMH batteries that require
minimal maintenance. The duration of a rechargeable NiMH battery depends on its frequency
and use. When used and maintained correctly the useful life of the battery is 5years or 500
charge/shock cycles.
Adequate maintenance of the battery implies taking the following considerations into account:
•Store the battery at temperatures less than 30 ºC and never expose the battery to high
temperatures, greater than 40 ºC.
•Periodically carry out complete discharges of the battery (it is recommended once a
month), for this purpose switching the device on without connecting it to any external
power supply, until the battery condition indicator lights up with a red color.
•If the battery of the device is left out of it for a long period of time, and is stored at a
temperature less than 30 ºC, recharge the battery every 6 months.
ATTENTION: Use only batteries supplied by OSATU or by its authorized distributors. The
use of another battery type can cause the device not to operate correctly.

TECHNICAL MANUAL DGG 700 B
9
WARNING: Storage of the batteries at temperatures greater than 30 ºC significantly reduces
their lifespan.
When it performs self-tests at start-up and during operation, the device checks the battery
charge giving the appropriate instructions in case its charge is low.
If on switching the device on, the battery indicator located on the front panel of the device is red
in colour at start-up, it indicates that it is necessary to charge the battery, for this purpose
connecting the device to an external power supply (car battery or AC mains).
WARNING: Danger of explosion. Do not recharge the REANIBEX Serie 700 batteries
outside of the device, since they could explode.
Store the new battery packs at temperatures between 0 ºC and 35 ºC. The optimum temperature
for storage of the batteries is 25 ºC.
When the battery is stored under ideal conditions, its capacity is equivalent to more than 130
discharges of 200 J, or more than 150 minutes of monitoring, or more than 120 minutes of
monitoring plus pacemaker stimulation at 60 mA and 60 bpm.
Changing of the device external battery is shown in the following drawing:
When the batteries are installed in the equipment, and this in turn is connected to an external
power supply (AC mains or car battery), the device continuously charges the battery, using an
internal charger.
