WARNING
Avoid shorting the battery. Do not mutilate or put a
fire. Use only approved charging methods.
The Model 4000M+ can be powered by the internal rechargeable nickel cadmium batteries or by AC line

panel and labeled POWER (see Figure 2-2).
The batteries charge whenever the unit is plugged in to an AC source. The batteries will fully charge in
approximately 6 hours, with the unit turned off, or in 24 hours, with the unit turned on. The batteries are
protected from overcharging.
