MilnakSkits S9 Overview
The MilnakSkits S-9 is a basic butt set that can be used to test telephone circuits. It can be found on-line for as little as $20. It may be sold under various brand names, such as the TelPal S-9 and the Zolicom Testset 100.
- It has enough features useful to many home owners and small office professionals.
- It includes a cable with both RJ11 connectors and tip/ring alligator clips.
- In includes an FSK "caller id" display, which can be useful for diagnostics
- It includes a standard DTMF keypad
- It is very compact and easy to carry
Limitations
Unlike, say, the well-featured Tempo TM-700, this set does have significant limitations:
- It does not report directly on faults. It's up the the user to do diagnostics using different tools.
- The build quality is weak. A few drops may render it non-functional.
- It is, in short, it a convenient low-cost POTS handset with caller-id and a non-traditional cable
Replacing the alligator clips with bed-of-nail style clips would be well worth it in my work.
MilnakSkits S9 Instructions:
My unit did not come with instructions, so these might help:
Interface
The jack on the bottom unit supports a single-pair, in RJ11 form.
Bottom switch
The bottom slide switch toggles the butt set between two modes:
Left: Default off-hook mode
Right: Default on-hook mode
Display:
The unit has an FSK / DTMF demodulator for displaying "caller id" data on its unlit on-board LCD panel. Diagnostics, like voltage and current, are not displayed.
Flash:
The flash button puts the butt set on hook for a at least of 500 ms. Longer on-hook times can be achieved by holding down the Flash button, or by using the bottom switch.
Keypad:
The keypad can be used to dial numbers using DTMF.
Opening the unit:
There are two small round covers on the back. Removing these covers reveals phillips-head screws. By removing these screws and snapping the case off from the bottom, it is possible to enter the device for service or repair.
Speaker and Earpiece:
If the switch is kept to the right-most position. the butt phone can be used as an everyday phone. The speaker and earpiece are suitable for day-to-day conversation.
