• Supply with batteries: 4 rechargeable NiMH 1.2V size AA
batteries, 1100/2100mA/h.
• Battery consumption: 130mA with display lighting always on.
• Continuous use time with 1300mA/h batteries 100% charged:
10 hrs approx.
• Communication speed of serial protocol for device programming:
1200 bps.
Batteries
Use only NiMh 1.2V size AA rechargeable batteries, with capacity
of 1000 to 2200mA/h.
Battery low warning
Hand-held programmer Art.1251/A is equipped with a battery
charge sensor, which sends a ‘battery low’ warning to the internal
control unit.
The battery symbol appears on the display to indicate that the
batteries need to be recharged.
From the moment at which the ‘battery low’ warning appears, the
hand-held programmer has a specific duration of battery life left,
after which the module must be connected to an external power
supply unit.

Changing the batteries
The batteries are housed in the battery compartment in the back of
the hand-held programmer.
To change the batteries, proceed as follows:
1. Switch off the hand-held programmer with the ON-OFF button
(figure 6).
2. Open the battery compartment as shown in figure 7.
3. Replace the batteries with fully charged batteries, taking care to
fit them the right way round as shown in the battery
compartment (figure 8).
4. Refit the cover on the battery compartment.
Recharging the batteries
To recharge the batteries, use a generic size AA NiMh battery
charger.
Note that the batteries are not recharged by the external power
supply unit that can be connected to the hand-held programmer.
The batteries can be recharged hundreds of times, but they
deteriorate over time.
If battery life between charges is significantly lower than normal,
buy new batteries.
