7.2. Recharging
The battery charge time is 5-7 hours. We recommend switching the SMP2 off
before charging the battery. The procedure is as follows:
• Plug the charger into an electrical outlet (110-240 V AC).
• Connect the charger to the SMP2. The red LED will light up. If it does not light
up, the charger is not properly connected.
• The battery is fully charged when the LED shows green. Disconnect the
charger from the SMP2 and unplug it from the mains.
The SMP2 has a battery charge controller so you can leave the device charging
for longer than the recommended 7 hours without harming the battery.
Note 1: We recommend fully charging the battery from time to time to ensure that
the battery is properly calibrated.
Note 2: If the red light begins blinking during the charge, it means that the battery
is too warm to be charged properly. Disconnect the charger, wait for at least one
hour and then reconnect the charger. If the problem persists, it could mean that the
battery is damaged.
