How long to clear US cheque with Al- Rajhi Bank ?

Previously I used  BCB or currently known as CIMB to clear all my US cheques (adsense, reviewme.com etc), but since I just recently open Al-Rajhi saving account, I decided to give them a try and if the charge is minimal I might continue to use them.

To deposit US cheque in AlRajhi Bank is similar to other bank process, go to ATM, insert your ATM/debit card and follow the instruction. But I confused a bit when the system ask for cheque amount in RM as US cheque is always in USD. So what is the solution ? Like what I did with CIMB many months ago, I just key in RM38.16 (my cheque amount is USD38.16).

If you have tried Al-Rajhi, share with us your experience.
