symbol, and it still indicates the visual alarm with white background in the upper limit. Press the
mute key again and you will hear the alarm sound.
Adjust the frequency of the simulator to 60 [1/min] again and observe the display. The heart rate indicator will diminish its value until 60.
When indicating less than 120 [1/min] the alarm sound and visual indication shall cease.
Similarly, and with the corresponding patient simulators, can perform verification of alarm operation of each parameter.
4.9. FUSE CHANGE
Before starting operation, make sure the device is disconnected from the power line, and also is off. To perform the operation must have
a small screwdriver and a set of replacement fuses.
You must enter a screwdriver to unlock the switch, pull the wire and cover will come out. Remove both fuses and check if are broken, by
measuring electrical continuity between the terminals (broken = no continuity). Should you find one or two broken, you must replace
them with new fuses.
ATTENTION! In case of fuses are damage replace with fuses of the same type and value. If the failure persists, please contact our
Customer Service.
ATTENTION! This equipment has line fuses in both the neutral pole and Phase Line.
4.10. RECHARGEABLE BATTERY
The device is provided with an internal rechargeable battery allowing it to operate without connection to AC line voltage or 12Vdc
external. To charge the internal batteries, connect it to the AC line voltage or external 12Vdc, permanently. It is not necessary that the
device is turned on to charge the battery. The battery charge is indicated on the front panel by turning on the green triangular light over
symbol.
The state of charge of the battery is indicated on the screen, and therefore requires that the device is on (MONITOR or energy selection)
and operating from the internal battery (disconnected from AC line or external 12Vdc).If the battery is charged, the display shows the
symbol. When the display shows the
symbol indicates that the battery is partially charged and should be charged as soon as
possible to preserve battery life.
When battery is discharged, the display shows the
symbol and the alarm sound is activated. When battery is fully discharged will be
displayed the message “Battery Discharged – Power is down” the technical alarm sound change and the device will automatically
turn off 120 seconds after the message, to avoid damaging the battery. The audible indication is detailed in section “Technical Alarms”.
In the latter case, the device will operate correctly from AC line or external 12Vdc, in both conditions, the display shows the symbol.
Battery Autonomy: This device, with new internal battery fully charged, at a temperature of 20ºC, can deliver a minimum of 150 shocks
at 200Joules without recharging the battery.
Battery Charging Time from exhausted till at least 90%: 2hrs 15min.
Charge Cycle: When is not used, the device must stay connected to AC line or external 12Vdc to recharge the batteries. There is no
need to disconnect from AC line or external 12Vdc, because it has an automatic device to keep the battery fully charged.
The internal battery should be checked visually once a year to determine there are no damages.
Check monthly its autonomy, if it decreases to 80% of the value indicated the technical specifications; the battery should be replaced
with another battery of the same type.
To ensure long battery life:
9
ATTENTION! No fully discharge the battery.
9
ATTENTION! Recharge the battery immediately after use.
9
ATTENTION! When the device is stored in warehouse, should be put to charge at least once every 60 days for at least
3hours at 25ºC ± 3ºC temperature, to prevent battery damage.
