Assembly errors
1. Faulty connections in Molex connectors
Excellent as these Molex connectors are, they can fail. The female contact feeler is retained in the connector shell by a tiny ‘tang’
engaging in a slot. If the tang has not engaged properly, the wire can work up in the shell and lose contact with the spike or post out of
the male header part of the connector. If pulling on the wire allows you to withdraw it from the shell, that’s where your problem lies.
Resolve the problem by bending out the tang and checking that the wire is now properly restrained.
2. Missing lights
TIM 2015 performs a test of all four LEDs at switch-on and then illuminates them individually as appropriate. If any of them fails to
illuminate consider, first check whether the LED wired the wrong way round (negative light from a reverse-connected LED is invisible to
the human eye). Is the LED faulty? Try substituting another LED. Is plug not making proper contact on the matching connector on the
PCB? If this is not the problem check (and reflow if necessary) the appropriate soldered joints on the PCB.
3. Pressing the left-hand control knob has no effect; in other words it does not take you into the Settings menu.
Solution 1: The pink wire from the encoder switch is not connected to the Encoder Molex connector. This may be due to a poor solder
joint on the encoder switch itself or a loose contact on the Molex connector. See Problem no. 1 above.
Solution 2: The wire connections to the encoder switch are incorrect. On the left-hand side the blue wire should be uppermost, with the
pink wire below. The right-hand side should have the brown wire on top, the mauve wire on the central solder tag and the yellow wire
at the bottom.
4. There is a discernible delay before audio is heard when switching on TIM 2015.
This is intentional. There is no audio output until the pips or toneburst is sounded for the first time. As you may switch on TIM 2015 at
any random moment a delay of up to eight seconds may occur until the next pips or toneburst moment.
