Sailor RT5022 VHF DSC
Subject:
Incorrect factory setting of power output in DSC and Distress-transmission.
Identification:
It has just come to our attention that in a limited number of RT5022 VHF DSC of recent
production the RF output power in DSC transmission has erroneously been set to 1W rather
than 25W, caused by an incorrect setup in the production final test equipment.
The serial number identification of units to which this erroneous power setting may apply
is found within the range of s/n 05737163 through s/n 05749592.
The incorrect power setting may be operationally verified by the <1W> indicator lamp in the
display lighting, when transmitting a DSC-call.
Action:
It is imperative that this DSC power setting be reset to 25W in all units identified within
the above mentioned serial number range as this power setting applies to the Distress
transmission also.
To accomplish the required reset of the DSC-transmission output power, a program has
been created that will automatically reset to correct power level. The procedure requires
the use of an SB5006 service tool. Follow the procedure described below to accomplish the
successful reset of the DSC power level to 25W.
NOTE: This procedure is applicable only to VHF radios with Main Release 1.30 software,
but otherwise harmless to other versions.
