Viark Sat 4K remote control

I have just got myself this receiver and am disappointed to find that there is no page up / page down buttons for going through channel lists quickly. Now I have to keep the up or down button pressed to fast-forward through the lists. The batteries will be drained quickly this way.

Is there any way to go up and down a page at a time on this receiver.
I can't believe the option to do this via the remote is no longer there for this receiver.
Definitely a backward step.

The remote for this receiver does NOT have the buttons for page up / page down.

My older model, Viark Sat DOES have these buttons.

There are no buttons for page up / page down.
Instead, there are buttons for channel up / channel down.
These just move you one position up or down in the channel list.
