Many customers found that they can‘t playback all channels. For example, if there are 4 channels, he can only select channel 1 and 2 but can‘t select channel 3 and 4.
This is because the system only can let you select 2 channels at the same time. You need to uncheck channel 1 and 2 first so that you can select channel 3 and 4.
For different models, the number of channels to playback recordings simultaneously is different. Here is the method where to find the model number.
Let us take DL81A as an example,
It can play 2 channels at the same time.
When it is playing 2 channels, you can see other channels are grey and can‘t be selected.
1. If you want to play other channels, you need to stop playing the current channel first.
2. Then uncheck channel 1 and channel 2. Finally, you can select another channel.
