SUBJECT :
SNOW NOISE / Memory Pack function up-grade
DATE : March 24, 2004
To announce the SNOW NOISE function and Memory Pack capability up-grade.
SNOW NOISE function doesn't work when there is broadcasting on CH69. Memory Pack doesn't work.
SNOW NOISE function tuned to CH69. This model has no capability for Memory Pack data copy.
for SNOW NOISE function: Software upgrade to 1.12 or greater (IC Symbol:IC004 on SMK0M302A-U2)+ memory value change It is possible to set the frequency between 44.0Mhz and 865.75MHz Here is the method how to set the frequency: example to set 855.25MHz(CH69) 1. Calculate (CH frequency + IF frequency)/0.03125 In case of CH69=855.25MHz (IF frequency is always 38.9MHz) (855.25+38.9)/0.03125=28612.8 2. Round off (if X>=0.5 then X=1, if X<0.5 then X=0): Round off 28612.8 ---> 28613 3. Change to hexadecimal: 28613=6FC5h 4. Memorise this value to the E2P ROM address 1FFEh and 1FFFh. 1FFEh: 6F (Upper byte) 1FFFh: C5 (Lower byte) (for example) CH60 (783.25): 66C5h CH45 (663.25): 57C5h CH25 (503.25): 43C5h CH20 (294.25): 29A5h 6. If set out of 4.0MHz - 865.75MHz, it is set to CH69 (855.25MHz). We can calculate if you send us the channel allocation in advance. Japan sent this software just for service purpose, not for production. Memory Pack capability: Software upgrade to 1.12 or greater (IC Symbol: IC004 on SMK0M302A-U2) + Hardware modification on page 3
