Information in 1.11 manual appears incorrect

I am having trouble using a suggestion in the 1.11 manual. I typed this precisely - recognizer.setSynthesizer(SYNTH_PICO) works perfectly!

Then - recognizer.setSynthesizer(SYNTH_PICO,"-1=en-US") - now 0 response (other than 2 beeps). From same manual just a bit lower than the first one??? Restarted MOVI and the first one works great, tried the second one again and nothing!!! What am I doing wrong??? firmware is 1.11… everything seems to work, just not example two.
