<p><P>PROBLEM TO BE SOLVED: To inform signal reception using a single indicator, to facilitate arrangement of the indicator to a case, and to achieve a configuration that is desirable from design point of view of. <P>SOLUTION: An MCU 30 detects, determines, and confirms which band is turned in a multiband receiver, or whether each band is simultaneously turned by detecting from level detection circuits 18, 18' in each of receiver circuits 4a and 4b. The MCU 30 controls the drive circuit of LEDs 41g and 41r corresponding to the signal reception state, thus emitting light in different colors by a multicolor luminescent indicator 41. Additionally, while an individual band is received, and a received frequency is a frequency in a memory channel, emission is made in color that differs from it, or the level of the frequency can be changed in the same system color for display. <P>COPYRIGHT: (C)2003,JPO</p> |
