SX52 TIMER programming problem using SX/B.

Hi All,
Has anyone used the SX/B TIMER commands for programming SX52. I have an old datacode SX52 from the very begining, (1999) an I like to use it for generating fix frequency using the chip TIMER. Although I'm familiar with assebly programming,·I dont want to waste time and use the SX/B to get it easy.
The problem is the use of TIMER1 R1,value command, by using TIMER compare mode. Changing the values it has·no effect on the output frequency. Changing the·TIMER prescale value is effected the output.
I don't know what can be the problem, my be the chicp is old (or dead)? or what?
I tried the TIMER2 and got the same result.
Has anyone a good working sample of programming the timers is SX/B? (If not I should code it in assembly.)

If you want to make a fixed frequency use "TIMER1 PWM, x, y".
For example, if you are clocking the SX @ 4MHz then "TIMER1 PWM, 2000, 4000" will create 1KHz frequency.
