Denon AVR5700 Owners Manual - Page 28

8 REMOTE CONTROL UNIT • The included remote control unit (RC-853) can be used to operate not only the AVR-5700 but other remote control compatible DENON components as well. Furthermore, it is equipped with a function for learning the control signals of remote control units of other manufacturers, so it can also be used to operate non-DENON remote control compatible video components. Inserting the batteries 1 Remove the remote control unit's rear cover. 2 Set two SUM3 (AA size) batteries in the battery compartment in the indicated direction. 3 Put the rear cover back on. Notes on Batteries • Use SUM3 (AA size) batteries in the remote control unit. • The batteries should be replaced with new ones approximately once a year, though this depends on the frequency of usage. • Even if less than a year has passed, replace the batteries with new ones if the set does not operate even when the remote control unit is operated nearby the set. • When inserting the batteries, be sure to do so in the proper direction, following the "" marks in the battery compartment. • To prevent damage or leakage of battery fluid: • Do not use a new battery together with an old one. • Do not use two different types of batteries. • Do not short-circuit, disassemble, heat or dispose of batteries in flames. • Remove the batteries from the remote control unit when you do not plan to use it for an extended period of time. • If the battery fluid should leak, carefully wipe the fluid off the inside of the battery compartment and insert new batteries. • When replacing the batteries, have the new batteries ready and insert them as quickly as possible. • The learned remote control signals may be cleared if no batteries are in the remote control unit for about 5 seconds. The factory-installed codes are in permanent memory, however. Using the remote control unit Approx. 7 m/22 feet 28 • Point the remote control unit at the remote sensor on the main unit as shown on the diagram. • The remote control unit can be used from a straight distance of approximately 7 meters/22 feet from the main unit, but this distance will be shorter if there are obstacles in the way or if the remote control unit is not pointed directly at the remote sensor. • The remote control unit can be operated at a horizontal angle of up to 30 degrees with respect to the remote sensor. NOTES: • It may be difficult to operate the remote control unit if the remote sensor is exposed to direct sunlight or strong artificial light. • Do not press buttons on the main unit and remote control unit simultaneously. Doing so may result in malfunction. • Neon signs or other devices emitting pulse-type noise nearby may result in malfunction, so keep the set as far away from such devices as possible.
