SECTION 11-BATTERIES Some basic concepts which will help you understand this automatic process are: The amount of electrical current drawn within a given time to charge a battery is called "charge rate". If, due to usage, the charge stored in the battery is low, the charge rate is high. As a charge builds up, the charge rate is reduced, and the battery charger rate decreases to a "trickle charge". NOTE: If the batteries need to be charged more often or take longer to charge than normal, they may need to be replaced. Contact a qualified technician. NOTE: The batteries can be charged using the on‐board battery charger or by plugging an independent battery charger into the port located on the front of the SPJ‐80/DPJ/MPJ joysticks. Battery Charger Operation ƽWARNING READ and CAREFULLY follow the manufacturer's instructions for each charger (supplied or purchased). If charging instructions are not supplied, consult a qualified technician for proper procedures prior to use. If the circuit breaker trips repeatedly, IMMEDIATELY unplug charger and contact dealer or a qualified technician. Three prong to two prong adapters should not be used. Using three prong adapters can result in improper grounding and present a shock hazard to user. On-Board Battery Charger ƽWARNING Use of improper extension cord could result in risk of fire and electric shock. When using an extension cord, use only a three wire extension cord having at least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating as the device being connected. Ensure the pins of the extension cord plug are the same number, size, and shape as those on the charger. DO NOT under any circumstances cut or remove the round grounding plug from the charger AC cable plug or the extension cord plug. NOTE: For this procedure, refer to FIGURE 11.4 on page 66. NOTE: Charge indicator light is only visible with rear shroud removed. 1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet. 2. The On/Off LED indicator illuminates solid RED indicating that the charger is on. 3. If the On/Off LED indicator is "Blinking" RED, this is abnormal. Unplug AC power cord from the on‐board battery charger and wall outlet. Contact Invacare at the number listed on the back page of this manual. Part No 1141450 65 Pronto® M91™ with SureStep®
