Let's take a look at the schedule.

Literal

Schedule-table [object-を] look-[try-てみる]-[volitional-ましょう].

A cheerful and natural everyday phrase. 見てみる stacks the te-form of 見る onto the auxiliary みる ('to try doing'), giving 'try looking at' or 'give it a look.' The ~ましょう (polite volitional) invites the listener to join. Note the appearance of two 見's in sequence — learners often find this double appearance confusing, but the structure is regular.
