SLEEP mode 
The ICOM-200/201 can be put into sleep mode if the Tiny-Tiger
®
 inside has a 
real time clock. In sleep mode the power consumption of the ICOM-200/201 is 
descreased significantly to just approx. 25mA. While in sleep mode, no BASIC 
program is executed by the ICOM-200/201. 
Sleep circuit 
The internal clock and SRAM of the Tiny-Tiger
®
 are buffered through a 
Goldcap. The power consumption of clock and SRAM is approx. 70µA, with a 
fully loaded Goldcap this is enough for about 3 hours. 
To use the SLEEP mode of the ICOM-200/201 Jumper J9, which is located 
under the LC display, has to be drawn. On delivery the jumper is inserted, so 
SLEEP mode is disabled.
