D When using the GPS receiver

•฀฀GPS฀signals฀cannot฀pass฀through฀metal฀objects.฀When฀us-

ing the ID-51A or ID-51E inside a vehicle, you may not re-
ceive GPS signals. We recommend you use it near a win-
dow. Please avoid the areas shown in the following:

฀ 1.฀DO฀NOT฀use฀where฀it฀will฀block฀the฀driver’s฀view.
 

2. DO NOT use where the air bags could deploy.

 

3. DO NOT use where it becomes a driving obstacle.

•฀฀The฀Global฀Positioning฀System฀(GPS)฀is฀built฀and฀operated฀

by the U.S. Department of Defence. The Department is re-
sponsible for accuracy and maintenance of the system. Any 
changes by the Department may affect the accuracy and 
function of the GPS system.

•฀฀When฀ the฀ GPS฀ receiver฀ is฀ activated,฀ please฀ do฀ not฀ cover฀

the฀ID-51A฀or฀ID-51E฀with฀anything฀that฀will฀block฀the฀satel-
lite signals.

•฀฀The฀GPS฀receiver฀may฀not฀work฀if฀used฀in฀the฀following฀loca-

tions:

 

1. Tunnels or high-rise buildings

฀ 2.฀Underground฀parking฀lots
 

3. Under a bridge or viaduct

 

4. In remote forested areas

 

5. Under bad weather conditions (rainy or cloudy day)

•฀฀The฀GPS฀receiver฀may฀not฀work฀if฀the฀transceiver฀operates฀

near the 440.205 MHz. This is due to signals made in the 
internal circuit and does not indicate a transceiver malfunc-
tion.

D Spurious signals

Depending on the combination of the operating band and 
mode, the Dualwatch or Triple-watch operation may generate 
certain spurious signals, or noise may be heard. These do not 
indicate a transceiver malfunction.

D About charging at power ON

ID-51A/E’s฀charging฀circuit฀charges฀the฀supplied฀battery฀pack฀
in approximately 3 hours. But with this rapid circuit, the bat-
tery฀pack฀cannot฀be฀charged฀at฀power฀ON,฀by฀default.฀So,฀be฀
sure to turn OFF the power before charging.
When “Charging (Power ON)”* is set to ON in the MENU screen, 
the฀battery฀pack฀can฀be฀charged฀even฀if฀the฀power฀is฀ON.฀(Only฀
when฀the฀battery฀pack฀is฀attached,฀and฀the฀optional฀CP-12L,฀
CP-19R฀or฀OPC-254L฀external฀DC฀power฀cable฀is฀connected฀
to [DC IN].) But this operation may generate certain spurious 
signals; the S-meter appears, or noise may be heard.
*MENU > Function > Charging (Power ON) (Default: OFF)

•฀฀Charging฀ time฀ period฀ at฀ power฀ ON฀ may฀ differ,฀ depending฀ on฀ the฀

operating condition.

•฀฀The฀external฀DC฀power฀supply฀voltage฀must฀be฀between฀10–16฀V,฀

and the current capacity must be more than 2.5 A  to charge the 
battery฀pack฀when฀operating.

•฀฀When฀you฀operate฀the฀transceiver฀while฀charging,฀and฀if฀you฀cannot฀

receive signals correctly, set “Charging (Power ON)”* to OFF, and 
disconnect the external DC power cable from [DC IN].
