What is a "Waiver" in a Rental Agreement

[Gene046]

WAIVER: LANDLORD'S failure to require compliance with the conditions of this agreement, or to exercise any right provided herein, shall not be deemed a waiver by LANDLORD of such condition or right. LANDLORD'S acceptance of rent with knowledge of any default under agreement by TENANT shall not be deemed a waiver of such default, nor shall it limit LANDLORD'S rights with respect to that or any subsequent right. If is further agreed between the parties that the payment of rent at any time shall not be a waiver to any UNLAWFUL DETAINER action unless LANDLORD in writing specifically acknowledges that this constitutes a waiver to the UNLAWFUL DETAINER action.

I'm confused about what this is trying to say. Can someone clarify, thanks in advance!

It means that if the landlord lets you off the hook for something, you can't later try to avoid compliance by claiming that he waived the requirement you previously violated.
