MTI 35-742 combo detector lights

Question

I have an email in to the mfg, but thought I would check here as I work on things I need to get done.

Installed a new 35-742 combo LP/CO detector. I have a green light on the CO and no light on the LP.

My belief is that I should have a green light on both of them if all is good.

Can anyone confirm that?

Should have only one green.

Yes only one green "Operational" LED,the other is red (always) and only comes on, or in conjunction with, green LED as visual alert.

Thanks all. I looked at the directions, but wasn't sure. Some of the pics in the web showed both lights green.
