4 GETTING STARTED NOTE Before operating the HX851 for the first time, it is recommended that the battery be charged. Please see section “4.1.4 USING THE CD-38 CHARGER CRADLE” for details. 4.1 BATTERIES AND CHARGERS If the radio has never been used, or its charge is depleted, it may be charged by connecting the CD-38 Charger Cradle with the PA-48B battery charger, as shown in the illustration.
Page 15
Battery packs should be charged only in non-hazardous environments; Use only STANDARD HORIZON-approved batteries; Use only a STANDARD HORIZON, (a Marine Division of YAESU USA) approved charger. The use of any other charger may cause perma- nent damage to the battery.

NOTE The CD-38 is only designed for the charging of the HX851’s battery, and is not suitable for other purposes. The CD-38 may contribute noise to TV and radio reception in the immediate vicinity, so we do not recom- mend its use adjacent to such devices.
The CD-38 contains three wires that are used to input or output NMEA 0183 information when the HX851 is inserted into the cradle. The HX851 outputs the following NMEA 0183 sentences at 4800 baud: GLL, GGA, GSA, GSV, RMC, DSC and DSE.
