Ryobi GD201 Operation Manual - Page 36

OPERATION NOTICE: This product is designed to be powered by either a RYOBI ONE+™ 18V lithium-ion (Li-ion) battery pack (DC mode) or by electric power (AC mode). The unit will operate in AC mode whenever it is connected to an electric power source. It will switch to DC mode when an approved battery pack is installed and the unit is not connected to an AC power source. CONNECTING THE GARAGE DOOR OPENER TO A POWER SUPPLY See Figures 65 and 66. For AC power:  Assemble and mount the garage door opener as described earlier in the Installation section.  Connect the garage door opener to an AC power supply. NOTE: Make sure the power supply is normal household voltage, 120 volts, AC only, 60 Hz.  Ensure that the power cord does not droop excessively or contact moving parts. For DC power:  Unplug the garage door opener.  Open the battery door.  Insert the battery pack into the product as shown.  Make sure the latches on each side of the battery pack snap into place and the battery pack is secured before beginning operation. WARNING: Make sure the latches on the battery pack snap in place and the battery pack is fully seated and secure in the battery port before beginning operation. Failure to securely seat the battery pack could cause the battery pack to fall out, resulting in serious personal injury or property damage. CHARGING A BATTERY PACK See Figure 66. Battery packs are shipped in a low charge condition to prevent possible problems. Therefore, you should charge them before first use. If the garage door opener does not charge the battery pack under normal circumstances, return both the battery pack and garage door opener to your nearest repair center for electrical check.  Connect the garage door opener to an AC power supply.  Install battery pack into the garage door opener as described earlier.  Press on the battery pack to be sure contacts on the battery pack engage properly with contacts in the garage door opener.  The battery pack may become slightly warm to the touch while charging. This is normal and does not indicate a problem.  When the battery pack is fully charged, you may remove the battery pack or leave it in the battery port to provide DC power if needed. Power Cord Battery Port Fig. 65 Latches  Close the battery door.  To remove the battery pack, open the battery door and depress the latches on both sides of the battery pack.
