●RX-491(２.４ＧＨｚ Spread spectrum transmission system receiver) is for compatible FH5 transmitter as M17.

   Other AM/FM/2.4GHz transmitter cannot use. 

●To combine with devices compatible with SSL can be changed setting by transmitter CODE AUX function.   

●Analog servos is not compatible with SUR , SSR, SHR mode. You must use analog servos by 

  NOR mode. If using analog servos by SUR, SSR, SHR mode, the analog servos will be broken. 

  (Analog servos: Hyper ERG series, RS-995, SZ-165T, SPEC series) 

   BL-RACER/BL-FORCE/BL-sport, F3300, F3000, F2200, SBL-01/02/03CR cannot work by SUR, SSR, 

   and SHR mode. You MUST use the ESC by NOR mode. 

●2.4GHz frequency band is not only for Radio Control. This frequency band is same as ISM (industrial, 

   scientific, and medical device) use.  There are some possible of interfering by the other devices as 

   Microwave, wireless LAN, digital cordless phone, audio device, gaming device, and bluetooth device, 

   and VICS. Also, amateur radio uses same frequency band. Please take care of interfering form

   other devices. In case of interfering to the radio station, please stop to use and avoid the interfere.

●Please check safe use and limit to use devices are possible to be interfered in RC circuit. 

   Also, please follow instructions by the facility manager.

●In case of running behind the building and steel tower, transmission function would be decline or

   out of control. Please always operate in visible situation. 

●If the 2.4GHz frequency band is saturated (too many transmitters on at once), as a safety precaution, 

   it may not pair when turned on. Once the frequencies have been cleared, or the saturation level has 

   dropped, your transmitter and receiver should pair when turned on without any problems.

*Receiver condition can be checked by the LED condition

●To combine with devices compatible with SSL can be changed setting by transmitter CODE AUX function.

●In case of using CODE AUX, please change AUX TYPE is [NOR] to [CODE5 or CODE10] in System.

  To choose CODE5 or CODE10 depends on device which is compatible with CODE5 or CODE10. 

●About CODE AUX, please refer SSL system explanation on our HP. (www.sanwa-denshi.com)

●Depending on the place receiver and antenna, reception distance may be different.

●Do not antenna tip is outside antenna pipe because of antenna protection. 

  Please put antenna in the pipe as right picture.

●MUST not hold antenna due to avoiding breaking of wire. 

  Do not pull off antenna. It will be caused failure inside receiver. 

●Please place antenna as high as possible in your model.

●Do not cut off and bundle antenna due to avoiding to decline receiver sensitivity.

●Stand antenna vertically. Please place receiver apart from motor and 

  FET Speed Controller (include leads).
